Transparent fish: photo and description. Salpa Maggiore - transparent fish
Nature constantly surprises us with rare and very interesting plants and animals. Among the amazing and unusual representatives of the fauna are many inhabitants of reservoirs. One of them is a transparent fish. This is one of the rare species that far from everyone knows about.
In order to survive, the fish are forced to mask themselves. The stripes and spots on the fins and the body, different colors of scales, as well as a variety of outgrowths help them to merge with the background that surrounds them. But there is one very extravagant and easiest way to become inconspicuous in the water. It becomes transparent, as if dissolved in the native element. To lose the color of the marine animal enough to lose the reflective surface, for example, mirror scales.
After all, the well-known fact is that the glass lowered into the water is almost imperceptible to the human eye. This way of masking was chosen for themselves and the most various fishes living in the seas and in fresh reservoirs. Moreover, these species often have no kinship with each other. "Glass" fish are found among aquarium.
New Zealand miracle
Fisherman Stuart Fraser, not far from the Karikari Peninsula, came across an unusual creature. At first, he took it for a crumpled cellophane bag that slowly slid over the surface of the water. Just looking closer, Stuart realized that it was a living organism. Until that time, the fisherman had not seen anything like this in the sea waters and at first did not dare to take the animal in his hands.
However, the curiosity of a man prevailed over fear. From the water they extracted a very strange and completely transparent fish. Her body was covered with unsteady jelly-like scales. That is why the transparent fish was more like a jellyfish. An amazing sea animal was virtually invisible and all internal organs, except for one small teardrop-shaped, painted in red. Fraser took a few shots of an amazing fish and let it go back to his native element.
New kind of inhabitants of the reservoir?
Pictures of the amazing creature Stuart Fraser showed Paul Castus, who occupies the post of director of the National Marine Aquarium. After studying the photos, he determined that this creature is nothing more than Salpa Maggiore is a transparent fish. This species looks similar to jellyfish, but nevertheless has a close relationship with marine vertebrates.
Salpa Maggiore is a transparent fish (see photo below). However, she has a heart and gills. In addition, inside this fish there are special filters. They pass water through her body, collecting food in the form of phytoplankton and algae.
Salpa Maggiore is a transparent fish traveling in large groups. The peculiarity of this species is that the individuals of this creature do not have sex. They are able to independently produce offspring, forming massive shoals.
Salpa Maggiore is a transparent fish (photo confirms its unusual appearance), and it looks like a creature from a horror movie. However, it should not be afraid. It is an absolutely harmless creature that feeds on plangton. The transparent body is only a disguise, able to protect the fish from the attacks of marine predators, which, like it, inhabit the surface layers of water.
Information about the fish Salpa Maggiore collected very little. Scientists attribute it to one of the subspecies of Salts, numbering about thirty species. In addition, it is known that these marine invertebrates prefer to live in the cold waters of the Southern Ocean.
The transparent fish Salpa Maggiore has a barrel shape. It moves through water by pumping fluid through its body. The jelly body of the fish is covered with transparent scales through which the annular muscles and intestines are visible. On the surface of an unusual creature you can see two siphon holes. One of them is oral, leading to the vast throat, and the second is cloacal. The siphon holes are located at opposite ends of the transparent body of the fish. On the abdominal side of the sea animal is the heart.
Amazing inhabitant of the Baikal waters
Unusual creatures are found not only in the seas and oceans. For example, there is a transparent fish in Baikal. This animal has no swim bladder and scales. In addition, thirty-five percent of his body is fat. Such fish lives in the great depth of the Baikal lake. Her individuals are viviparous.
What is the name of the transparent fish of Baikal? Golomyanka. This name comes from the Russian word "holomen", meaning "open sea". It surprisingly accurately conveys the existing features of the etiology of this species of fish.
Golomyanka has subtle bones of the skull. It has especially developed dorsal, pectoral and anal fins. Golomyanki very prolific. One individual can produce almost two thousand fry. Reproduction occurs by gynogenesis, which is characteristic only for this species.
The transparent fish of Baikal is able to withstand enormous pressure equal to one hundred twenty-five bars. Only for this reason its dwelling place is the bottom of this deep reservoir.
Eat fish using a passive method. Golomyankas literally hover in the water with their pectoral fins. At the same time, their mouth is constantly open and is able to instantly seize passing food in the form of benthic amphipods, epicures and acropectopus and other food.
It is believed that the fat of the golomyanka was used in ancient times as a lamp oil. This transparent fish played a major role in Chinese and Mongolian medicine. During the wars, she was caught in order to recuperate the wounded soldiers.
"Glass" fish are also found among fairly well-known species. They are also among the representatives of the perch family. Ambassidae is one of the subspecies of these fish, otherwise called glass Asian. These aquatic vertebrates are characterized by a high and short torso, somewhat thickened from the sides. In the area of the neck they have some concavity. Transparent tissues of these fish allow you to see the skeleton, as well as shiny films that are covered with the gills and internal organs.
The long kosits on unpaired fins has a transparent fish, the name of which is the glass angel. Representatives of this family do not have scales on the body. However, the most extravagant appearance has a large perch. Above the head of this fish hangs a huge discoid growth, resembling a hump.
Most often for the house get Parambassis ranga. This is an indian glass perch. This fish has received an unjustified reputation for being uneasy and capricious in its content. This opinion was formed on the assumption that she prefers to live in brackish waters. Of course, some members of this family actually live in the seas. However, the Indian glass perch - a resident of low-flowing fresh water. This fish prefers some sour and soft water. Under such conditions, it will easily take root in the aquarium and will not give its owner unnecessary trouble.
However, it should be borne in mind that glass Indian perch like to eat natural food and refuse to cereal. In addition, to keep in the home aquarium preferably a flock of ten or more fish. The fact is that lonely individuals or living in small groups become very fearful and oppressed. In addition, their appetite is getting worse.
This is another transparent fish for the aquarium. Despite its name, it is impossible to recognize it as close relatives of the catfish living in our waters. The body of these fish is compressed from the sides, not vertically. This is because the Asian glass soma does not lie at the bottom. They actively move in the water and live in flocks. Transparent tissues of the body allow you to see the filaments of the ribs and the thin spine of these amazing fish. At first glance, it seems that the abdominal cavity with internal organs of these individuals is absent altogether. However, it is not. All of them are displaced to the head and look like a continuation of the gills.
Glass soma can not only be Asian. There is also an African species of these fish, belonging to the family shilbovyh. Outwardly, they have an incredible similarity with their Asian namesakes. However, they are not so transparent and are distinguished by longitudinal black stripes stretching along the sides of the body. Another distinctive feature of this family is the remarkably developed adipose fin, as well as four, rather than two pairs of antennae on the head.
Decorate a home aquarium and small fish of the Characidae family. Their torso is colored with only a small palette of colors. As a rule, these are only individual pigmented areas that are barely noticeable on the faded background of the body. Such spots are peculiar identifying marks. They flash only at those moments when the light hits them at a certain angle. These sudden spots, playing with all the colors of the rainbow, look great in a slightly darkened aquarium. However, in this family there are absolutely transparent fish. You can see only the swim bladder in their body in the light. Nevertheless, this fish has a decoration. It is represented by red tail at the base, and a thin strip of greenish color, elongated along the body. To keep such a fish is easy even for beginners, as it is undemanding to aquarium conditions.
This is a relatively large fish as close as possible to the ideal "glass". Her tall, diamond-shaped body has a slight golden hue.
The transparency of this fish is not used at all for masking from enemies. The fact is that the harax itself is a predator. In order to wait for prey passing by, this fish is able to spend long hours in ambush. The transparent body makes it invisible in water. At the same time, the harax hangs absolutely motionless in the thickets of aquatic vegetation headfirst.
Ridley's regular istella
On the anal and dorsal fins of this fish there are spots of yellow and black colors. Its tail has a reddish tinge. But, despite this coloring, it is still classified as a transparent fish. "Glass" is her body. Only in the abdominal cavity, you can see the stomach and intestines of the fish, as well as the gills located behind the gill covers.
Indian glass perch is known as transparent fish. Recently, the fish are increasingly divorced in aquariums. Among the reasons for the popularity appear peace-loving character and unusual appearance. Even a novice owner of an aquarium can successfully manifest a pledged potential, properly caring for a fish.
The fish has a diamond-shaped high body, different oblate shape on the sides. Unique color explains the name, which has the property to the characteristic "transparent". The body of the fish is transparent, as a result of which the internal organs are highlighted from a certain angle of view. The fish can surprise with a beautiful silvery shade. Females and males have differences in color. What differences should be noted?
- Males most often are green with a yellow tint of color. In this case, the presence of blue fins is assumed. Among the additional differences are dark transverse stripes.
- Females have the usual silver color. Border is missing. Despite the lack of fringe, females can amaze with their beauty.
- Fish have reddish fins located on the chest. Some individuals are surprised by the presence of a lilac stripe, which begins next to the gill cover and stretches to the base of the tail.
- The spine includes 25 vertebrae, and the presence of rays can be noted on the belly and back.
- The shape of the swim bladder turns out to be different from nature. Males have a pointed bubble, females - round.
- The frontal part has a concave shape. For this reason, the lower jaw, where small teeth grow, can protrude forward.
- The dorsal fin has two parts, and the front is higher and has a triangular shape. The back of the fin has a rounded shape.
- At the bottom is the anal fin, which visually resembles the dorsal.
- The tail fin has a deep incision, as a result of which it resembles a mermaid's tail.
- In nature, glass perches can grow up to eight centimeters. However, aquarium specimens grow only up to five centimeters.
The fish may be peaceful, but it is also characterized by a tendency to fear. It is recommended to abandon a densely populated aquarium, since such living conditions immediately lead to severe stress.
Fish can live on any water level. Moreover, it can stay in a fixed state for a long time, and in such situations one should not be afraid for the health of the pets. After a time, the perch will certainly make a jerky movement and move to a different location point. Wanting to observe the behavior of fish, you need to select at least eight individuals and provide them with a large aquarium. If there is enough space, the males can define personal territories where they will look forward to the females for breeding.
High-quality care will allow the fish to live from two to three years.
What conditions are best to create?
- The minimum size of the aquarium is 50 liters, 60 centimeters.
- Acidity should be 7-8.
- Temperature - 22 - 26 degrees.
- Optimum rigidity - 9 - 19.
- Care should be taken of quality filtration and aeration of water.
- It is advisable to carry out a water change every week. It is recommended to use small portions.
It is important to note: transparent fish show an increased sensitivity to the state of the water, its characteristics, because living conditions in an aquarium should be given increased attention. In the ideal case, the water should be hard, slightly alkaline and have the addition of sea salt.
Features glass aquarium perch
Among the important tasks is the correct design of the house for the fish. What rules should be considered?
- For soil you need to choose sand or fine dark gravel. In the first case, the sand should be dark river, in the second case - gravel fine and polished.
- It is assumed the presence of snags, pebbles of natural, artificial houses, mangrove roots, caves.
- Perch prefer bright light, because the aquarium is best located next to the light source.
- There should be a lot of plants. Recommended dense planting. When choosing plants, you need to make sure that they are resistant to salt water. Green areas can be pre-planted in pots. It is advisable to use a rodentary, fern, valisneria, Javanese moss. Dense plants will be a place to shelter and incubate spawning.
- In the aquarium, it is desirable to create as many nooks as possible. This is due to the following factor: during mating, the males try to choose the optimal place for laying eggs. Subsequently, the site is carefully protected from other fish.
- Nooks also help the fish to retire. The male can begin mating dances, seeing the female and inviting her to the bush for further spawning. The optimal ratio between females and males is 1: 2.
Under natural conditions, the basis of food is made by worms, larvae, crustaceans and insects. The diet in aquarium conditions is changing. What foods are recommended for Indian glassfish?
- Small crustaceans.
- Dry frozen food can be given, but it will not enjoy love.
It is advisable to feed the fish in portions of small size from three times a week.
How is breeding?
Aquarium fish can breed. For successful breeding it is recommended to create special conditions that are optimal for the inhabitants of the aquarium.
Sexual maturity perch comes to 4 - 6 months. The optimal time for breeding is early spring or late autumn, because it is at this time that the food becomes the most useful and nutritious. Otherwise, the fish will face difficult feeding of fry.
For one pair of fish will need to use spawning from fifty centimeters, for groups of fish - from eighty. It is assumed unfolding floating plants, pots with small-leaved plants. The creation of such secluded places contributes to the convergence of fish, making reproduction becomes a simple and enjoyable task.
For one male, 2 females will be required. This ratio will allow a couple of times to increase the number of offspring and reduce the risk of conflict between the inhabitants of the aquarium.
A couple of months before breeding need to do water. It is recommended to regularly add a teaspoon of salt to six liters of water. In addition, it is desirable to raise the temperature by two to three degrees. In the aquarium now you need to add fresh and clean water, which is previously settled.
Spawning traditionally occurs in the morning, because the fish need to provide sunlight in the morning.
Most often it turns out about two hundred eggs. Впоследствии самка их мечет по шесть - десять единиц. Самая ответственная задача в это время - защитить икринки от поражения грибком. Для этого нужно использовать слабый раствор сини метилена, так как он позволяет обезвреживать грибок без лишних усилий. Затем икра прикрепляется к корягам, зеленым насаждением. В это время самок и самцов желательно пересадить в другой аквариум.
Продолжительность инкубации составляет от трех до четырех дней. Then there are fry, which in 3 months have time to grow to 1.5 centimeters. Juveniles may be silvery. Initially, the fry keep in one flock, but soon part.
After three to four days, the fry can feed on rotifers, cyclops, and diaptomus nauplii. Feeding is advisable to carry out minimal portions regularly throughout the day.
Juveniles most often do not seek active life in an aquarium, but soon begin to swim more intensively.
Fry have a weak body, so you need to remember the importance of observing the following factors:
- In the aquarium water can be added only by drip technique.
- Lighting and aeration should be permanent.
- Any, even the slightest, temperature changes are prohibited.
- Before cleaning the aquarium you need to turn on the side lamp, attracting small fish in the opposite direction from the desired one.
Observing the above aspects, you can protect babies from all sorts of risks.
For life in aquarium conditions, about ten individuals will fit at the same time, since this number allows the inhabitants to feel confident and safe.
Glass Bass - Aquarium Fish
Love anatomy? Want to see the structure of the body right through it? Or have you always dreamed of seeing through objects? If so, then there is a fish that will simultaneously satisfy all these needs and desires. Small, exotic and ... absolutely transparent glass perch. Further, it goes about him.
Lovers of aquarium art, this type of fish is well known, but for beginners it will be to its liking for its unusual and exceptional, because it stands out among all the other inhabitants of the aquarium.
It is possible that at first the perch will be lost against the background of brighter and more variegated neighbors, but only until the first detection. Then it's hard to lose sight again. He stands out for its inconspicuous. Contradictory, right? But this is its main advantage.
This small exotic fish was brought to Europe at the beginning of the 20th century from Asian countries such as India, Pakistan, Thailand and Bangladesh.
In Russia, it appeared a little later, and until 1941 it was bred in special fish breeding shops of zoo plants.
Glory and popularity among aquarists of the whole world fish owes its absolutely transparent body, through which all the insides and bones are visible.
The body is flat, high and has an unusual diamond shape, the forehead is slightly concave, the teeth are small, the bite is abnormal, that is, the lower jaw is pushed forward.
The dorsal fin consists of two parts: the first is triangular and pointed, the second is long and rounded. The anal fin is symmetrical in shape to the second part of the dorsal. The tail cut is pretty deep.
How to distinguish male and female
The gender of an individual can be determined by the shape of the air bubble visible through the transparent skin of the fish:
- in males it is a little pointed,
- females more rounded.
On the side there are 5 transverse bands, which are formed by black spots.
The girls are painted more modestly and mostly have a silver-steel shade of scales.
In nature, fish grow up to 8 cm in length, but in the aquarium they reach only 5 cm.
Marketing move. Caution
Many sellers are capable of anything to sell inconspicuous goods. For the sake of profit, they are ready to go to great lengths, caring little about the health and longevity of the aquarium fish. So, some merchants paint animals to make them look even more unusual.
On the Bird Market, you can often find perch with multicolored bright stripes on the back and other parts of the body. And the colors are chosen with unnatural intensity for nature: bright green, purple, juicy red or orange from a series of pluck eyes. The brighter the better! Seasoned aquarists are not fooled by this marketing ploy, but beginners can easily get caught.It is worth remembering that any staining of living fish is a chemical and artificial process associated with the piercing of the thin skin with a needle, and any violation of the integrity of the integument adversely affects the health and health of the pet, not to mention the introduction of multi-colored chemicals.
Over time, the paint will still fade and will be removed by the immune system. Such a decorated fish does not live for a long time, and instead of 2-3 years (normal life expectancy in aquarium conditions) it will last 2 months. If you do not want your purchase to turn into disappointment, do not purchase a fuchsia-colored glass perch. And remember that any natural paint is better than bright artificial.
Conditions of detention
Another indisputable plus of glass perch is its unpretentiousness and peacefulness. It is equally well tolerated by fresh or slightly salted water, so if he gets the sea neighbors, the perch can easily adapt to them.
For the content of glass perch can withstand the following parameters:
- aquarium with a volume of 50 liters,
- water temperature should be 22-26 ° C, gH 8-20, pH 7-8.5,
- You can add salt in the calculation of 3-4 Art. l 10 liters of fluid.
Water should be old, that is, settled for a week. Therefore, you need to take care of the next batch with each replacement.
Filtration and aeration is also an important condition. In the wild, glass perches prefer the middle and upper layers of water bodies, they will not like the gloom and dusk in their new home. Therefore, additional lighting aquarium will not be superfluous, and even better to put it so that sunlight falls directly on it.
Compatibility with other fish
By its nature, the perch is a schooling fish, therefore in the aquarium it is better to keep at the same time about 10 individuals. So they feel more confident and safe. Peaceful nature allows the fish to get along with any inhabitants of the aquarium, except for aggressive and predatory representatives of the fauna.
Ideal freshwater neighbors will be
- bull bees,
- Nannakaras and rasbory,
- and the sea, preferring salted water, will be guppies and mollies.
Making a perch aquarium
As a primer, in order to emphasize the unusual natural beauty of the glass window, dark river sand or fine polished gravel with logs, stones or artificial houses placed on it are optimally suited.
There should also be a lot of plants. Thick green plantings of the aquarium serve as fish not only as a shelter, but also as a place for spawning.
And there should be a lot of such nooks, because during the mating period the males, first of all, choose a place for the future laying of caviar (most often it is a bush of some overgrown small-leaved plant) and zealously protect it from the invasion of other males.
If the female gets in his field of view, the perch begins its marriage dances, inviting it to the bush for spawning. The ratio of females and males in the pack should be 1: 2.
Problems with feeding should not occur, as the perch is unpretentious in food. In nature, he eats live food, but in the aquarium he can eat artificial. However, be prepared that such a diet may lead to infertility of the fish.
To avoid this, try to give live or frozen food. A pet will enjoy eating with a moth, a pipe maker, a carriage, or a daphnia, and the cyclops will not refuse either. Feed should be given in small portions throughout the day, but at least 3 times a week.
Individuals reach sexual maturity by the age of six months. Having chosen a secluded place for spawning and having invited a female there, the male will violate reproduction.
The mating period lasts for 3-4 days, during which the female spawns, quickly fertilized by the male. At one time, the female can lay up to 6 eggs, and in a total of up to 200 pieces.
After fertilization, parents can be removed from the aquarium or left, since they do not pose a danger to eggs and newborn fry.
To stimulate spawning, you can add 12 liters of water to 2 tsp. salt, increase its temperature by 2-3 degrees and add ¼ part of fresh distilled water.
The incubation period lasts two or three days, after which the fry are already beginning to swim. It is then that they need to be given rotifers or nauplias of diaptomus. At fourteen days of age, the young should be transferred to Cyclops nauplius and small diaptomus.The first 2 weeks of life of the fry are the most important. If it is possible to feed them during this period, then it will be easier later, and the issue of food will be solved by itself.
During feeding, the young should be set in motion by the flow of water. Food should always be in the water, so you need to give it in small portions during the day.
By the first three months of life, fry appear first sexual characteristics.
"Cheap and angry!" - the glass perch motto. Very unpretentious and calm pet. Among the inhabitants of the aquarium will always be peace and quiet. An ideal start for a novice aquarist.
Glass perch - a crystal shard in an aquarium
The Indian glass perch comes from the genus Khanda of the centropomov or Robal family, inhabiting fresh and brackish, slow-flowing water bodies of Cambodia, Thailand, Nepal, Burma, and India. Fish gained popularity in aquariums as a peaceful creature with a remarkable appearance. The content of this perch at home is amenable to lovers of different experiences.
The fish has a diamond-shaped high body, compressed on the sides. This perch owes its name to a unique natural color. His translucent body casts a silvery tone, highlighting the internal organs and spine. Males are colored in yellow-greenish shades with dark transverse stripes and fins edged with blue. And the color of the females is an ordinary silvery without a border on the fins. The pectoral fins of the fish are reddish, and in some representatives a lilac stripe stretches from the gill cover to the base of the tail. The spine of the fish consists of 25 vertebrae, on the abdomen and back there are rays. In males, the swim bladder is pointed, in females it is rounded.
The forehead is concave, so the lower jaw with small teeth protrudes forward. The dorsal fin is divided into 2 parts, the anterior higher and triangular in shape, while the posterior fin is more rounded. From below, the anal fin repeats, as in a mirror image, the posterior part of the dorsal fin. The tail fin has a deep incision, resembling a mermaid tail. In nature, glass perches reach 8 cm, and in aquariums up to 5 cm. They live for 2-3 years with quality care.
By the nature of the fish peace-loving, but fearful. Experiencing stress in a densely populated aquarium. Therefore, its content is optimal in the species aquarium. The fish keeps on any water levels, it can be stationary for a long time, and then abruptly make sudden movements. To observe the behavior of these perches, it is better to take from 8 pieces of fish and place in a container with a minimum number of plants and free swimming space. With enough space, perch males can establish personal territories and wait for females.
These fish contain in the tank from 50 liters and from 60 cm. Water parameters: acidity 7-8, temperature 22-26 ° С, hardness 9-19 °. High-quality filtration, aeration and water change in small portions weekly. The fish is sensitive to changes in water parameters, therefore its constant content in clean water is important. Perch like hard and slightly alkaline water with the addition of sea salt.
For soil it is better to choose sand or dark fine gravel. This fish loves bright lighting, it is important to place the aquarium close to the light source. Plants need to be planted thickly, they are selected for resistance to salt water and planted in pots. Vallisneria, whipweed, Javanese moss, ferns will do. Fishes need shelters, snags, caves. As decorations you can lay out mangrove roots and large stones.
In nature, this fish feeds on worms, insects and their larvae, crustaceans. In aquarium conditions, with appetite, it eats live food in the form of bloodworms, daphnia, cortex, cyclops, enhitreus and small crustaceans. Also uses frozen food, but dry eats reluctantly. Feed them in small doses from 3 times a week.
Glass perch matured by 4-6 months. Breeding fish is better to postpone for the rainy season - a period of early spring or late autumn, when the starter feed for fry will appear in the form of nauplius diptus. Otherwise, there will be difficulties with raising offspring. For one pair of producers, spawning from 50 cm is taken, for group spawning from 80 cm. Floating plants or pots with small-leaved plants are laid out, perlon threads are also suitable.
On one male take from 2 females. 2-3 months before the start of reproduction, you need to add salt to water - 1 teaspoon per 6 liters. Also raise the temperature by 2-3 degrees and add fresh distilled water. Spawning occurs in the morning, so it is necessary to ensure the fish access to the morning sunlight. Usually it turns out about 200 eggs, which the female throws by 6-10 pieces. In order to avoid caviar exposure to a fungus, it is recommended to lower a weak methylene blue solution into the aquarium. Caviar is attached to a different surface: plants, snags and other objects. Then the producers are removed to another aquarium, although these fish are not prone to cannibalism.
The incubation period lasts up to 3-4 days, then fry appear, growing up to 1.5 cm by 3 months. Juveniles are painted in silver color, holding a flock, but as the groups grow, they disintegrate. After 3-4 days, the fry can freely eat the nauplia of diptomus, rotifers and cyclops. However, these fish are not very active, so feeding is done in small portions during the day so that the fry can always find food in the aquarium.
When growing fry in an aquarium, water is added by a drip method, providing constant illumination and aeration. You can not change the temperature regime, why the fry may die. If necessary, clean the tank, you can turn on the side of the lamp, to the light of which the fish will gather and allow you to get out of the other side of the aquarium.
The content of glass perches is optimal with its congeners. You should not combine them in an aquarium with aggressive or larger neighbors. Calm and peaceful fish such as corridors, mollies, guppies, tetras and rasbor will do.
There are several species of fish related to Indian glass perch, which can be confused with it because of their transparent appearance. Do not buy multi-colored individuals subjected to artificial injections of dyes that cause irreparable harm to their health. This fish is like a piece of shiny glass shard, its presence will certainly become a bright attraction of the aquarium.
Are there transparent animals?
jellyfish, fish - For the first time transparent fish were described in 1856. Then they were considered a separate species. But later studies have shown that these leptocephals are just one of the stages of development of acne. It is by the presence of such a larval form that it is possible to classify these fish.
In addition, there are glass perches, glass catfishes and tetras, as well as the Baikal golomyanka (as they say it can be read through the newspaper: - (...) Glass fish
frogs - Japanese and South American - Japanese crossed a pair of brown Japanese frogs (Rana japonica) with a genetic mutation, due to which the skin of wilts becomes transparent. Then they conducted experiments on the selection of their offspring and, ultimately, derived a "transparent" frog breed.
The skin of the resulting amphibians maintains transparency throughout their life cycle.
It seemed little to the Japanese and they created a transparent fish - according to scientists, it will allow to study the structure of the fish without cutting its body, that is, the scientists finally found a humane way to study the structure of animals, since the scales of fish do not have pigments, it is completely transparent and any person can observe the work of the heart and other organs, which, of course, is amazing.
Deep-water glass squid (Teuthowenia pellucida) lives in the waters of the southern hemisphere.
Transparent crustaceans Fronima (Phronima) and many other amazing transparent creatures.
These are mostly marine inhabitants, but some can also be found on land. Here are some examples:
Fish with a clear head:
Deep-water glass squid:
Transparent animals are living creatures with clear, glass-like skin; they abound in different ecosystems around the world. These fascinating organisms on the verge of invisibility - the material ghosts of the real world.
* Unusual fish macrospin microstoma. The most amazing creature ever found in the depths of the ocean. Because of its strange appearance, it is sometimes called a "ghost fish", which is not surprising, since it has a completely transparent head.

11 amazing transparent animals (photo).
Бочкоглаз - рыба с прозрачной головой
Малоротая макропинна or бочкоглаз - единственная рыба в мире, имеющая прозрачную голову. Она была открыта и описана в 1939 году ученым Чепменом, однако фотографии живой рыбы были получены лишь в 2004 году. Actually, then it became known about the features of the structure of her head, as the previously fragile transparent dome collapsed when the macropinnas were extracted from the water.
Malorotya macropinna didn’t let zoologists sleep well for a long time. Her transparent head and unusual cylindrical eyes for them remained a mystery.
Thanks to the transparent shell on the head, the fish can observe what is happening around it. But the biggest surprise was her eyes. Looking at the image, guess where they are located?
The openings over the mouth, which you probably thought to be the eyes, actually turned out to be organs of smell. And what is inside the transparent head and very much resembles 2 green hemispheres, in fact turned out to be the eyes of a fish. They are separated by a thin bone septum.
In the light of his eyes become a bright green color. This is due to the content in them of a special yellow pigment, which provides filtering of light and reduces its brightness. I want to remind you that many deep-sea fish have poorly developed eyesight. This cannot be said about the macropinnu, so she should take care of her eyes from the bright light she may encounter when climbing for prey in the upper water column.
The bright green eyes of this small fish (it does not exceed 15 cm in length) are in the head chamber filled with clear liquid
This chamber is covered with a dense, but at the same time elastic transparent shell, which is attached to the scales on the body with small macropinnas. Since the special structure of the eye muscles is characteristic of a small macropinni, its cylindrical eyes can be both upright and horizontal, when a fish can look directly through its transparent head.
Thus, the macroponna can notice prey, and when it is in front of it, and when it floats above it. And as soon as the prey, usually zooplankton, turns out to be at the level of the mouth of the fish, it rapidly grabs it.
Despite the fact that since the discovery of this amazing fish, it has been possible to learn a lot about it, it still remains poorly understood. In many respects this is due to the fact that the low-m. macropinna lives at a very great depth. Usually this fish is found at a depth of 500 to 800 meters, however, it is believed that it can live at a much greater depth.
Most of the time macropina spends motionless, or slowly moving in the water. Until recently it was thought that the peculiarity of the structure of her eyes is such that the fish cannot rotate them. However, this was only partly true. Floating horizontally, her eyes always look upward, straight through the transparent dome. Noticing the prey above itself, macropina has to take a vertical position in the water so that the eyes turn forward. After that, she can control the process of absorption of prey, that is, she knows what time to open her mouth.
Although short macropina is a predator, it can not catch large enough prey for its size. This is due to the fact that it has a small mouth and a small number of teeth. Therefore, the fish is content with small fish, crustaceans, as well as tentacles of poisonous siphonophores. It is possible that the emergence of a transparent dome, covering the eyes, is just an evolutionary device for protection against the poisonous tentacles of its prey.
The world learned about this fish only in 1939, when it accidentally fell into the fishing nets. William Chapman took up her study and primary description. But because of the deep-sea habitat, it was not possible to study this fish in more detail, and you will take very little from one sample. In addition to this, with a sharp change in pressure (from the depth to the surface), its transparent shell protecting the eyes broke.
And only in 2004, scientists were able to see this fish in its natural habitat at depth. This was made possible by scientists from the Monterey Bay Aquarium Research Institute and the deep-water apparatus "ROVs", with which the video was shot and the first images of clear-headed fish were taken.
The body of this small fish, 10 to 15 centimeters long, is covered with dark scales. Despite the big gulp, the mouth of the fish is quite narrow, which is why it has to monitor the size of the prey. When swimming in a horizontal position, the tubular eyes of the fish are always directed upwards. Thus, she looks out for prey in the upper layers.
And after 5 years, in 2009, they also managed to catch several specimens of fish and watch their behavior in a special aquarium. And here are the results of the scientists. It turns out that the tubular eyes of the fish can rotate. This happens during a hunt, when a fish, noticing a prey, places its body vertically.
Various crustaceans, siphonophore tentacles, cnidaria, and other zooplankton were found in their stomachs. Slowly swimming in the water column, the fish looks up. As soon as she notices a tidbit above herself, she swims under it and moves the body vertically to grab the prey. At this point, her eyes move 90 °, leaving the prey in sight.
Judging by the fact that she has to deal with the poisonous stinging tentacles of the siphonophore, the integuments of this fish are immune to their venom, and the eyes are reliably protected by a transparent shell.
Fish lives with a transparent head in the subarctic and temperate waters of the Pacific Ocean: the Kuril Islands, northern Japan, the Bering Sea, the western coast of Canada and the United States, as well as in the region of the Gulf of California.
