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

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 thorns. different size, ribbon-like leathery outgrowths that are on his body, 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 is an ideal habitat for this fish. It also actively inhabits swampy or sandy water areas.

Lifestyle

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

It is worth noting that most of their lives they are in shallow water, in a slight current with a water temperature of at least +25. The current carries a huge amount of plankton necessary for food. Movement in water is carried out with the help of a vertebral fin, which performs more than 30 strokes in one second.

Nutrition

His diet is very poor, 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. IN warm water it is no more than 14 days, and in the cold 28 days. To feed the fry, the male releases 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 damage 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

IN 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 has family ties with needle fish. An inhabitant of salty tropical waters is also found off the coast of Eastern Canada and Great Britain. Some species 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 features 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 swim by itself, so a small current is needed for a comfortable life.

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.

In the coastal waters of 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.

Black Sea sea ​​Horse is a native inhabitant of the Black Sea, formed in separate view about 20 million years ago. Nature rewarded him with an original appearance, and in the course of evolution, unique opportunities and skills inaccessible to other inhabitants underwater world. Human actions have put skates on the brink of extinction, forcing biologists to add them to the Red Book.

Description

In biological encyclopedias, the Black Sea seahorse is named Hippocampus guttulatus (long-snouted seahorse) and belongs to the class of ray-finned fish. Its upper part is similar to a chess "horse", and the elongated tubular mouth-pump (one third of the length of the head) only enhances the resemblance. The head is located perpendicular to the body and can move up / down, which other types of fish are not able to do. The eyes work independently of each other, and the viewing angle reaches 300 degrees.

The body of the seahorse is elongated and slightly flattened laterally and is constantly in an upright position due to a double air bladder, the upper section of which is smaller than the lower one. It ends with a long and flexible tail without a blade-fin, capable of curling into a ring. They skates cling to algae, hiding from danger or attacking prey from an ambush.

For protective purposes, the body of the seahorse is covered with horny plates, spikes of various lengths and growths, which serve as an additional means of camouflage in thickets of algae. The shell is of high strength and does not lose its properties even after drying. Having a brownish-yellow color with small white dots, they are able to change color, adjusting to the environment.

Seahorses swim vertically and not very fast, making up to 70 “strokes” per second with their dorsal fin, helping themselves with oscillatory movements of the body and tail. Under the head there are two more small fins, corresponding in their functions to the pectoral fins of fish of "standard" forms.

Male seahorses are usually larger and grow up to 20-21 centimeters, females up to 17-18. The usual life expectancy does not exceed 4-5 years.

Habitat and food

The seahorse lives in the waters of the Black, Azov and Mediterranean seas, off the eastern shores Atlantic Ocean, from the Netherlands to the African coast. It chooses places with a depth of up to 20 meters, with the obligatory presence of underwater vegetation, where it spends about 90% of its life, setting up ambushes and hiding from predators. Prefers water without strong currents.

They mostly live in small groups of 3-5 individuals, almost never gathering in large quantities. But they can also create couples for life, especially when living in artificial conditions aquariums. At the same time, if one of the partners dies, the second mourns very much, which is noticeable by the change in behavior, and may also die.

The seahorse feeds with the help of a mouth-pump, drawing food along with water at great speed, from distances up to 4 centimeters. He eats small bottom inhabitants of the sea, crustaceans, fish fry, plankton, which he catches from ambush in algae. It is worth noting the appetite of animals that “lunch” at least 5 times a day and are able to do this up to 10 hours a day.

An interesting fact: in seahorses, males, not females, bear and give birth to offspring.

Spawning

Unlike most animals, males are responsible for the reproduction of seahorses, who bear and “feed” the eggs, give birth to offspring. At the same time, the females carefully choose the future father, and their mating dances may last 3 days. At this time, the skates swim in shallow water (up to 4 meters), swim together, periodically rising to the surface, exchange songs from click sounds, and even “kiss”, touching their pump mouths.

When the prelude ends, the female lays eggs (depending on size, from 10 to 650 eggs). For this, at the bottom abdominal cavity the male is provided with an egg bag-pocket penetrated by the circulatory system to supply oxygen to the developing larvae. After filling (sometimes the pipit accepts eggs from several females), its seam closes and overgrows, and the “father” carries out internal fertilization of the eggs.

The gestation of eggs takes about 4-5 weeks. All this time, the seahorse is in shallow water, without leaving square meter his "personal" area, where he hunts and hides. This is his territory, where even “frivolous” females leave to provide the “nursing father” with enough food.

After the formation of fry, completely ready for independent life, difficult childbirth begins - the male can wriggle up to 2 days, trying to open the birth bag. Sometimes it ends with his death. If everything went well, the little skates crawl out of the pocket and rise to the surface for a breath of air (to fill the air bubble), then return to the "daddy". For some time they live next to him, hiding in a "bag" in case of danger, but soon they swim away and never return.

Use of seahorses

Seahorses are used by man in several areas, one of which is aesthetic in nature. Vacationers willingly buy these original species of animals for souvenirs. Black Sea coast, or try to "domesticate" them by planting them in an aquarium. In the second case, death is also almost inevitable, since skates do not tolerate changes well, especially if their “half” is left in the sea.


Sea Horse

Another area in which seahorses are widely used is ethnoscience especially among the peoples of Asia. According to traditional healers, drugs from animals help in the treatment of baldness, skin diseases, atherosclerosis, cough and asthma. Especially popular means in the treatment of impotence and disorders of sexual functions. The ability to bind harmful carcinogens in the human body and toxic substances which helps in the prevention of cancer.

The seahorse is a genus of small marine bony fish family of marine needles of the needle-shaped order. The number of species of seahorses is about 50. The unusual shape of the body of a horse resembles a chess piece of a horse. Numerous long spikes and tape-like leathery outgrowths located on the body of the seahorse make it invisible among algae and inaccessible to predators. The sizes of seahorses range from 2 to 30 cm, depending on the species to which a particular individual belongs. An interesting feature seahorse is that their offspring is carried by the male.

The taxonomy of the seahorse is very confusing due to the unique ability of these fish to change their appearance - color and even body shape. The closest relatives of seahorses are small fish - sea needles, which have much in common in the structure of the body with skates. However, the body shape and manner of movement in the water of sea "horses" is completely unusual.

The body of seahorses in the water is located unconventionally for fish - vertically or diagonally. The reason for this is the relatively large swim bladder, most of which is located in the upper body of the seahorse. It is impossible to confuse these graceful and colorful fish, similar to jewelry or toys, with any inhabitant of the water element.

The body of a seahorse is not covered with scales, but with bone plates. Barbed armor protects them from danger. The armor is so strong that it is almost impossible to break even a dried dead animal. However, in his shell, he is so light and fast that he literally soars in the water, and his body shimmers with all the colors of the rainbow - from orange to bluish blue, from lemon yellow to fiery red. By the brightness of the colors, it is just right to compare this fish with tropical birds and brightly colored coral reef fish.

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. Typically, seahorses wrap their tail around a twig of coral or a tuft of seagrass and spend most of their 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.

They feed on plankton. They track down the smallest crustaceans, 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 have only three small fins: the dorsal fin helps them swim forward, and the two gill fins maintain vertical balance and serve as a rudder.

In a moment of danger, seahorses can significantly speed up their movement, flapping their fins up to 35 times per second (some scientists even call the number 70). Masterfully they succeed and vertical maneuvers. By changing the volume of the swim bladder, these fish move up and down in a spiral. However, seahorses are not capable of swimming fast - they are considered the record holders for the slowest swimming among known fish. Most of the time, the seahorse hangs motionless in the water, catching its tail on algae, coral, or even the neck of a relative.

Skates can ride "on horseback" on fish. Due to their curved tail, seahorses can travel long distances. They grab the perch's fins and hold on until the fish swims into the algae. And the skates grab their pair with their tail and swim in an embrace.

The eyes of seahorses are large, the vision is quite sharp. Their tail is crocheted to the stomach, and their heads are decorated with horns of various shapes.

The eyes of skates move independently from one another. The organ of vision in a seahorse is similar to the eyes of a chameleon. One eye of these fish can look forward, and the other can see what is happening behind.

Seahorses have the ability to change the color of their body, which allows them to skillfully disguise themselves in thickets and among the bottom landscape. A lurking seahorse is almost impossible to see in ambush unless you look very closely. The ability to disguise is necessary for seahorses both for protection and for successful hunting, because they are active predators.

In the seas washing the shores of Russia, seahorses are represented by only two or three species - the Black Sea seahorse: found in the Black and Seas of Azov, as well as the Japanese seahorse living in the Sea of ​​Japan. Occasionally in the Black Sea you can meet a long-snouted seahorse, common in the seas of the Mediterranean basin. For permanent residence seahorses choose quieter places; they do not like rough currents and noisy tidal waves.

Seahorses are monogamous fish, they live couples, but periodically can change partners. Characteristically, these fish bear eggs, with males and females changing roles. IN 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. The fertility of different species ranges from 5 to 1500 fry. Newborn fish are completely independent and move away from the parent pair.

Among the seahorses there are also very small representatives, a couple of centimeters in size, there are also, in a way, giants up to 30 centimeters long. The smallest species, the pygmy seahorse, is found in the Gulf of Mexico. Its length does not exceed four centimeters. In Black and mediterranean seas you can meet a long-faced or spotted seahorse, the length of which reaches 12-18 centimeters. The most famous representatives of the species Hippocampus kuda, which lives off the coast of Indonesia. Seahorses of this species, their length is about 14 centimeters, are painted brightly and variegatedly, some are speckled, others are striped. The largest seahorses are found near Australia.

The life expectancy of seahorses is, on average, 3-4 years. The extreme survivability of these fish is known - being taken out of the water, they can live for several hours and return to normal life if they are released into their native element.

natural enemies seahorses have few - its body is extremely bony and covered with bony formations. Therefore, it is hunted only by a large land crab, which is able to digest such indigestible prey. Seahorses are not dangerous to humans. This is a peaceful harmless fish, besides it is very small.

Man himself is a great danger to seahorses. Today, seahorses are on the verge of extinction - their population is rapidly declining. 30 species of seahorses out of 32 are listed in the Red Book, known to science. There are many reasons for this, and one of them is the massive capture of skates off the coast of Thailand, Malaysia, Australia and the Philippines. Exotic appearance fish doomed them to the fact that people use them as souvenirs and gifts.

A separate point in the decline in the number of seahorse populations is the fact that the taste of these fish is extremely appreciated by gourmets. Liver and caviar of seahorses are considered a delicacy, although they have some laxative properties. A seahorse dish costs up to $800 per serving in some restaurants.

Great amount seahorses (according to some estimates - up to 80 million horses a year) are used in the countries of the Pacific region of Asia and in Australia for the production of medicines and potions. These medicines are used as pain relievers for coughs and asthma, and also as a remedy for impotence. IN last years This Far Eastern "Viagra" has become popular in Europe. ABOUT healing properties people have known seahorse meat since ancient times. Seahorses have been used to prepare various medicines and potions in many countries.

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.

Seahorses can sing. During mating games they perform peculiar dances around their partners and partners and accompany themselves with clicking sounds, the tempo of which can change.

Based on anatomical, molecular and genetic research it was revealed that the seahorse is a highly modified pipefish. Fossilized remains of seahorses are quite rare. The most studied fossils of the species Hippocampus guttulatus (synonym - H. ramulosus) from the formations of the Marecchia River (Italian province of Rimini). These findings are dated to the Lower Pliocene (about 3 million years ago). The earliest seahorse fossils are considered to be two Middle Miocene needle-like species Hippocampus sarmaticus and Hippocampus slovenicus found in Slovenia. Their age is estimated at 13 million years. According to the molecular clock method, the species of seahorses and needlefish split in the Late Oligocene. There is a theory that this genus appeared in response to the emergence of large areas of shallow water, which was caused by tectonic events. The appearance of vast shallows led to the spread of algae, and, as a result, the animals living in this environment.

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 of bony fish (family of sea needles) of the needle-shaped order. Looking at this fish, the chess piece of a horse immediately comes to mind. Long neck – distinguishing 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. Unusual structure the tail allows the seahorse to cling to seaweed and coral 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.

It is interesting that the seahorse is a caring father and faithful spouse. 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 of a giant 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.
