The seahorse is a fish that is unique in nature and has an interesting body shape.

At first glance, it is very similar to one of the most recognizable chess pieces.

There are more than 50 species of these creatures in the world, but only thirty-two species have been studied in detail.

In addition, anthropologists have made sensational conclusions based on the found prehistoric fossilized remains, they say that in the past it is a specifically modified needle fish.

An interesting ability of these marine life thing is the male becomes the breeder. The process itself will be discussed in detail a little later.

Appearance

The appearance and body structure of this species of fish are able to adapt to any environment a habitat. Once in the territory that strongly betrays her appearance, she immediately changes the appearance of her color in a few minutes like a chameleon and merges with the underwater environment.





His body is endowed with many spikes of various sizes, ribbon-like leathery outgrowths that are on his torso, are also able to hide him in sea ​​depths from the eyes of predators and potential prey.

There are at least two popular types of these wonderful creatures. The dwarf skate has a body length not exceeding 2.5 cm. It lives in the Gulf of Mexico, and the Malayan species of skates is quite larger than its aforementioned counterpart, its body length can reach up to 25 centimeters.

The small mobility of this fish is provided by its eyes, which have a remarkable ability. Eyeballs are able to move independently of each other, thereby increasing horizons.

Range and habitat

This species is common in places with subtropical climate from the coast of Indonesia to Australia. It also lives along the Atlantic coast of Europe, North America and Africa. Little-studied species live in the waters Pacific Ocean closer to the US coast.

Habitat

Overgrown sea shallow water perfect place residence for this fish. It also actively inhabits swampy or sandy water areas.

Lifestyle

This fish is predominantly solitary and sedentary image life, so as not to drift during high and low tide, it clings to algae or corals with its flexible and powerful tail.

It is worth noting that most their life they are in shallow water, on a slight current with a water temperature not lower than +25. The current carries great amount plankton for food. Movement in water is carried out with the help of a vertebral fin, which performs more than 30 strokes in one second.

Food

His diet is very meager, the daily menu includes:

  • plankton;
  • small fish
  • crustaceans;
  • shrimps;

He himself becomes a victim of enemies very rarely, as he is a master of disguises. Thanks to this, the victim, not noticing the danger, approaches him herself, having a tubular snout, the skate is able to suck it in at a distance of three centimeters.

Enemies

Due to its anatomical structure of the skeleton, not every enemy is able to digest its many small, but very strong bones.

Land crab - is the single most dangerous and ruthless enemy for this species of fish.

reproduction

The reverse distribution of roles between male and female makes this species even more mysterious. The breeding season in tropical warm waters can be all year round, in the cold - in spring and summer.

During the mating season, the male makes sounds resembling finger snaps so that her gaze falls on him. After a while, the female reciprocates and approaches him. Taking this opportunity, we want to invite you to listen to our huge collection of sounds from the category:.

In a special pocket, located under the tail of the male, the female throws in a huge amount of fertilized eggs, providing him with further care for future offspring, and she herself disappears away to mate with other males.

The term for the development of caviar may be different, this is due to the temperature of the water. AT warm water it is no more than 14 days, and in the cold 28 days. To feed the fry, the male secretes a special liquid into his bag.

When the offspring matures, the male releases the fry already able to swim into the wild. Their number depends on the species, the minimum of them can be 50, the maximum is more than 1000 individuals.

Many people wonder: why is the seahorse in an upright position? We decided to investigate and answer this interesting question. .

The reason is as follows; the stabilizing swim bladder of this fish is located along the entire body and is divided by a septum that separates the upper body from the rest.

As a result, the head bladder is larger than the abdominal one, it is this arrangement of the bladder that provides the fish with a vertical position.

Red Book

Irreparable harm to the taxon is caused by fishing trawls that destroy the seabed along with the environment. natural habitat marine organism.



Currently, all types of skates are listed in the Red Book and are strictly protected by law. Reasons for this abound, for example; while you are reading this post, illegal fishing for this exotic creature is underway off the coast of Malaysia. In these countries, it is a delicacy and is very popular among tourists..

Lifespan

AT wild nature this interesting view fish can exist no more than 7 years.

Related species

To date, the closest relative of our hero is the stickleback fish.

  1. Some species of marine organisms are threatened with extinction.
  2. Floats in an upright position.
  3. Souvenirs depicting this fish are actively purchased by tourists in East Asia.
  4. The liver and eyes of this fish are considered a delicacy; in fish restaurants, a serving of this dish can cost up to $1,000.
  5. The male himself is engaged in the withdrawal of offspring.

The seahorse is an unusual animal resembling a small magic horse ranging in size from 1.5 to 30 centimeters. It is related to the needle fish. An inhabitant of salty tropical waters is also found off the coast of Eastern Canada and Great Britain. Separate types exist in fresh waters. The sea dweller is of constant interest to children and adults.

Appearance

Sea Horse - Interesting Facts for children about appearance. The movement involves a small fin on the back, oscillating up to 35 times per second. Rowing with two gill fins maintains vertical balance. They are weak swimmers, some dwarf species move at a speed of one and a half meters per hour. Spiraling up and down provides a change in the volume of the swim bladder.

They are able to change color depending on the surrounding plants, therefore they are invisible in aquatic environment. The body is covered with bony armor instead of scales. Like tropical birds, they have a rich color palette with stripes and specks. They are difficult to distinguish from corals.

Observation is carried out by a pair of eyes that can look in opposite directions.

Beautiful representatives of fish breathe with the help of gills, have a swim bladder located throughout the body, which makes it possible to vertically position themselves in the water.

A peculiar tail helps to attach to the fins and make long journeys “on horseback” on other fish.

Behavior

Interesting Seahorse Facts - Behavior. Due to the peculiarities of the digestive system, they need constant nutrition, which enters the body with water. Food is not only plankton, crustaceans, shrimps, larvae, but also small fish. There are no teeth and stomach, absorption occurs through the proboscis. They do not chase prey, but patiently wait for it to sail by itself, so for comfortable life need a little flow.

Life expectancy is limited to 4-5 years, but they manage to leave a million offspring.

They don't do well in aquariums. The reason is an unusual environment, susceptibility to stress. They need a lot of small living creatures for food: more than 3 thousand crustaceans and shrimps per day. Without food, they quickly die from exhaustion.

The female transfers the eggs from her body to a special bag to the male. Thus, males carry offspring for 1.5 months. This is one of the few species when dad is worn with a child. The number of fry ranges from 1600 to 2, depending on the species. Born cubs immediately go on an independent journey.

The main enemies of the skate are crabs, penguins, rays and other hungry predators. Almost the entire body is made up of bones, scales, and spines. Few want to feast on such prey.

Red Book

For several years, the unique fish has been a symbol sea ​​power Northern Fleet. It was displayed on the emblem of Zaozersk, a city in the Murmansk region. Then the image of the skate was replaced with a dolphin.

AT coastal waters In Russia, there are 2 species of fish that live in the Black, Azov and Japanese Seas.

The Red Book lists 30 species of animals out of 32. Their habitats are still being polluted, and numerous jellyfish destroy their nutrient plankton. The reason for the mass capture is a beautiful appearance.

One out of a hundred fry is able to grow to maturity. The causes of extinction are related to economic activity of people. Fish are caught by the Chinese, Filipinos, Indonesians for pseudo-medical purposes (of course, these creatures cannot cure anyone) and making souvenirs from dried exhibits.

Seahorse liver and eyes are considered a healthy delicacy and are served in expensive restaurants. Fried skates on sticks offer Chinese cuisine.

The breeding of these creatures is successfully carried out in the zoos of Berlin, Stuttgart, Basel, in the California and the National Aquarium of Baltimore.

Seahorses are very peculiar fish with an outstanding appearance and interesting biology. They belong to the needle family of the order Kolushkoiformes. Such an affiliation is not accidental, because seahorses, one might say, are brothers of others. interesting fishsea ​​needles. A total of 50 species are known. seahorses, a few of the most large species called sea dragons.

Herbal sea ​​Dragon, or rag-picker (Phyllopteryx taeniolatus).

The appearance of seahorses is so unusual that at first glance it is difficult to recognize them as fish. The body of the skates is intricately curved, the back sticks out like a hump, the abdomen also protrudes forward, the front part of the body is thin and curved like the neck of a horse (hence the name). The head is small, its anterior part is elongated with a tube, the eyes are bulging. The tail of seahorses is long and very flexible; in a calm state, the fish twist it into a ring or twist the stems around their tail. aquatic plants. The body of the skates is covered with various thickenings, bumps, outgrowths and similar decorations. The color of these fish is often of the same color, but different species are colored very differently. In any case, the coloring of each species very accurately imitates the color and texture of the surface on which this skate lives. Skates living among aquatic plants are often brown, yellowish, green; seahorses living among corals can be red, bright yellow, purple.

Seahorses are masters of the art of camouflage.

In addition, each fish can change its shade to some extent. Seahorses are small fish, ranging in size from 2 to 20 cm.

Most small view- the pygmy seahorse (Hippocampus bargibanti) is only 2 cm long. It is completely indistinguishable from coral branches.

These fish live in the seas of tropical and subtropical zones. Their range covers the entire Earth. Seahorses live in shallow waters among seaweed beds or among corals. These are sedentary and generally very inactive fish. Seahorses usually wrap their tail around a twig or tuft of coral. sea ​​grass and spend most of the time in this position. But large sea dragons do not know how to attach themselves to vegetation. For short distances they swim holding the body vertically, if they have to leave the "house", then they can swim in an almost horizontal position. They swim slowly. In general, the nature of these fish is surprisingly calm and meek, seahorses do not show aggression towards fellow tribesmen and other fish.

The intricately decorated leafy sea dragon (Phycodurus eques) is indistinguishable from its surroundings.

They feed on plankton. The smallest crustaceans they track, rolling their eyes funny. As soon as the prey approaches the miniature hunter, the seahorse puffs out its cheeks, creating negative pressure in the oral cavity and sucks the crustacean like a vacuum cleaner. Despite their small size, skates are big eaters and can indulge in gluttony up to 10 hours a day.

Seahorses are monogamous fish, they live couples, but periodically can change partners. Characteristically, these fish bear eggs, with males and females changing roles. AT mating season in females, a tube-shaped ovipositor grows, and in the male, thickened folds in the tail area form a bag. Before spawning, partners perform a long mating dance.

The female lays the eggs in the male's pouch and he incubates them for about 2 weeks. Newborn fry exit the pouch through a narrow opening. Sea dragons do not have a bag and carry eggs on the tail stalk. Fertility different types ranges from 5 to 1500 fry. Newborn fish are completely independent and move away from the parent pair.

Currently, many species of seahorses have become very rare, and some are even on the verge of extinction. This is facilitated by the massive catch of these fish and their low fertility. They catch seahorses for their meat, which is used in cooking. Eastern countries and in oriental medicine. In addition, souvenirs made from dried seahorses are very popular. Keeping seahorses in aquariums is not very easy, they are demanding on food and prone to disease, but it is very interesting to watch them.

how a male seahorse gives birth to fry.

It's hard to believe, but in ancient times, seahorses were feared and considered chthonic creatures. The Chinese are sure that skates return male power, and Europeans decorate their aquariums with them.

Underwater chameleons

Unlike other inhabitants of the oceans and seas, seahorses swim in an upright position and in pairs, often with their tails tied. At the same time, they, like chameleons, avoid a few enemies, imitating the color of underwater plants.

The last property is due to the fact that seahorses are inept swimmers. They have a small fin on their back that makes up to 35 movements per second, and pectoral fins, which are more correctly called rudders. And the pygmy seahorse is generally recognized as the slowest fish in the world. It moves at a speed of 1.5 meters per hour.

good eaters

Seahorses have neither teeth nor a stomach. Them digestive system resembles a ramjet engine, so they have to eat constantly so as not to die of hunger. As a rule, they cling to algae with their tenacious tails and suck up water at a distance of up to three centimeters, and along with it - simple food. Every day they consume three thousand or more brine shrimp (planktonic organisms). They also love a tiny fish, carefully watching it. Interestingly, both eyes of skates can look in different directions, studying the environment.

Close relative - needlefish

However, there are not so many who want to eat the seahorses themselves, except perhaps penguins, crabs, tuna, stingrays and some of the very hungry predators. The thing is that seahorses are very poorly digested due to excessive boneiness. Their numerous long spikes and band-like leathery outgrowths are also not pleasant for absorption. As genetic studies show, the ancestors of seahorses are the same needle-like progenitor from which the needlefish appeared. The division into two species occurred approximately 23 million years ago.

Non-stress resistant

The greatest danger to seahorses is a strong pitching, leading to exhaustion and complete loss of strength. They like calm and clear water. Interestingly, these fish are very susceptible to stress. In an unusual environment, they die quickly enough, even if they have food. That is why they do not take root well in aquariums. Interestingly, seahorses are monogamous, are faithful partners and are not separated from each other all their lives. After the death of one of them, the widow or widower grieves greatly, which can even cause death.

Lady's choice

The role of the male in choosing his half is secondary. The female herself decides who should make her a couple. Seeing a suitable candidate for a wife, she tests him for passion for three days. She intertwines with him in a dance, and rises to the surface of the water to sink again to the bottom. In the literature, this phenomenon is described as a "dawn dance". This happens multiple times.

Between themselves, future partners exchange clicking signals. The task of the male is to keep up with the dancing girlfriend. If he fails, the bride looks for another groom. It is believed that this is how the female tests the strength of the male. If the choice is made, then the seahorses begin to mate.

pregnant dad

Seahorses are faithful partners and are not separated from each other all their lives. At the same time, the male himself bears his cubs, being the only creature on earth who has a so-called male pregnancy.

The mating dance lasts eight hours and is accompanied by a color change. In the process of mating, the female transfers the eggs to the partner in the brood pouch on her stomach. It is there that miniature seahorses are formed within 40-50 days. From 5 to 1500 fry can be born.

By the way, some scientists argue that the expression "pregnant male" is not true. The fact is that the duty of the "sea horse" is to protect the fertilized eggs. During this period, the female visits the male once a day for 6 minutes of "morning greeting", and then sails away until the next morning. In captivity, this routine can be broken.

For good health

Before middle age only one out of a hundred fry survive. In fact, this figure is one of the highest for fish. AT recent times The greatest danger to seahorses is man, in particular, about 20 million of these fish are caught annually by the Chinese for traditional medicine primarily for the treatment of impotence.

It is also claimed that a decoction of them helps to overcome nocturnal enuresis. Seahorses sell for an average of $600 to $3,000 per kilo. There are times when these dried fish were exchanged for gold by weight one to one. In addition to the Chinese, Indonesians and Filipinos also catch seahorses. As a result, almost all types of seahorse are listed in the Red Book. And a species such as the Paradoxical Seahorse is considered extinct.

Don't crucian, don't perch,
Has a long neck
Who is he? Guess soon!
Well, of course, horse!

Seahorse (from lat. Hippocampus) a small cute sea fish unusual shape from the genus bony fish(family of marine needles) of the needle-shaped order. Looking at this fish, the chess piece of a horse immediately comes to mind. Long neckdistinguishing feature skate. If you disassemble the horse into parts of the body, then its head resembles a horse's, the tail is a monkey, the eyes are from a chameleon, and the outer integuments resemble those of insects. The unusual structure of the tail allows the skate to cling to seaweed and corals and hide in them, sensing danger. The ability to mimic (camouflage) makes the seahorse almost invulnerable. The seahorse feeds on plankton. Young skates are quite voracious and can eat for 10 hours in a row, eating up to three thousand crustaceans and shrimps. The vertical position of the seahorse relative to the water is its distinguishing feature.

Interestingly, the seahorse - caring father and faithful husband. The heavy burden of motherhood falls on the shoulders of the male. The seahorse independently bears the cub in a special bag, which is located in the lower part of the abdomen of the seahorse. It is there that during mating games the female introduces caviar. If the female dies, the male for a long time remains faithful to the partner and vice versa, if the male dies, the female remains faithful to the male for up to 4 weeks.

Dimensions

The size of a seahorse varies from two to three centimeters to 30. Thirty centimeters is the size giant representative seahorse. The average size is 10 or 12 centimeters. The smallest representatives - pygmy seahorses have about 13 or even 3 millimeters. With a size of 13 centimeters, the weight of a seahorse is about 10 grams.
