What does a seahorse rag-picker look like. Seahorse rag-picker. What is so unusual in the appearance of a rag-picker seahorse

To the question What does a RAG-PICKER look like? given by the author IOSHAN the best answer is Ribbon-like leathery outgrowths on its body resemble either leaves or feathers and help it to remain unnoticed by predators in thickets of algae. His Latin name Phyllopteryx is composed of two words: phyllon - leaf and pteryx - feather, wing. Literally, leaflet.
He earned his name with an unusual appearance: outgrowths in the form of ribbons, patches and some incomprehensible “scraps” depart from the body, head, fins, and all this trembles and sways to the beat of the waves. The color of the seahorse, of course, is indistinguishable from the color of Sargasso algae.
a horse - a rag-picker - and without hide and seek in algae will be saved. It looks like it's all torn, tattered. If he swims, it is not difficult to mistake him for a rag or a piece of seaweed. Rag-pickers are most diverse off the coast of Australia.
Skates do not swim like a fish, but glide gracefully, holding their heads and upper part body vertically. How does a horse move itself? It turns out that the dorsal fin, which quickly sways from side to side, like a fan. Skates swim slowly, therefore they do not run away from enemies, but hide, disguising themselves among algae and changing their color depending on the natural background. And the rag-picker was originally made up of numerous long spikes and ribbon-like outgrowths and outwardly looks like a branch of Sargasso algae, in the thickets of which he lives.
When for seahorses there comes a time mating games, they are singing" . The sounds of mating duets are reminiscent of snapping fingers. So the male invites the female to lay eggs in his brood pouch, which is located on his belly and opens outward with a small hole. After the eggs are laid, all worries about bearing offspring fall entirely on the shoulders of the male skate. The number of embryos hatched by one pipit is small - from 20 to 200, however, the offspring born in the pouch to the stage of a viable larva have many chances to survive.
Like the seahorse, the leaf dragon gets its name from its resemblance to another (albeit fabulous) creature. Its size, of course, does not reach a real dragon, but compared to a seahorse, it is a real giant, it grows up to 45 cm. Plankton, algae, and floating debris serve as food for a leafy dragon.
Unlike seahorses, male sea dragons do not have a brood pouch. Like their close relatives, female dragons lay up to 120 ruby-red eggs, which are then fertilized and attached in a special place under the tail of the male. During pregnancy, couples approach each other every morning and have a kind of love dance with a change in skin color towards brighter shades. 4-8 weeks pass, and the birth of small dragons occurs ( exact copies adults).
Leaf dragons are in danger of extinction due to industrial emissions, as well as becoming part of the collections of divers fascinated by their appearance. In connection with this danger, the species is taken under the protection of the Australian government.
The less famous grass sea dragon (Phyllopteryx taeniolatus) is similar to its leafy counterpart, but its yellow and red outgrowths are unsightly and weed-like, hence the name. They are mainly found in Australian waters off the coast of New South Wales and Victoria.

A small fish - a rag-picker seahorse lives on shallow depth among aquatic plants, in shape and color it resembles algae. Name the type of its protective device against enemies, explain its meaning and relative nature. 1) the similarity of the animal with the motionless natural object- a plant is called patronizing resemblance(imitation); 2) a seahorse hangs among aquatic plants and is invisible to predators; 3) when the fish moves or in open space, it becomes accessible and noticeable to enemies.

Rag-picker (lat. Rhycoredurus eques) - ray-finned sea ​​fish from the needle family (lat. Syngnathidae). The presence of many leaf-like growths gives it a very original look, making it look more like a plant than a fish.

It is also called the rag-picker seahorse, although zoologists have identified this miracle Yudo in a separate genus Rhycodurus, which is translated from Greek means "like seaweed tail".

Spreading

Rag-pickers live in cold sea ​​waters on the south coast of western and southern Australia. Their range extends sporadically from the surrounding area Australian city perth before national park Wilson's Promontory on the peninsula of the same name in Victoria.

Fish settle at depths from 3 to 30 m on the border of sandy beaches and coral reefs. Unlike seahorses, they do not attach themselves to plants, so they are often washed ashore during a storm. From this point of view sand beach much better than coastal rocks.

Behavior

The color of fish is completely dependent on environmental conditions. In shallow water, they are painted in sandy or olive color. The rag-pickers living on great depths, predominantly dark brown or brownish red. The body length of adults reaches 35 cm. It is extremely rare to come across specimens that have managed to grow up to 50 cm.

The rag-pickers feed on small crustaceans, with a particular focus on shrimp and mysids. They swim very slowly with the help of small translucent fins. Their tail is motionless.

In an hour, these sea slugs move only 100-140 m.

Despite their inactivity, they are almost invisible among underwater vegetation, so they rarely get to dinner with predators.

The rag-picker has no teeth, it swallows its prey whole. During the day, the fish eats up to 3 thousand mysids. He likes to eat protein foods with marine herbaceous plants from the genus Posidonia.

reproduction

Spawning takes place in winter. To continue the family, rag-pickers gather in shallow bays. At this time, females can be easily distinguished from males by their large swollen bellies.

The female lays 250 to 300 eggs, which are attached to the tail of the male.

The eggs are 7 mm long and about 4 mm in diameter. The tail of the new parent acquires a yellowish tint. Happy and proud fathers slowly go into deep waters to devote themselves to the pleasant chores of raising offspring.

Young fish hatch from eggs after about 8 weeks for 6-7 days. Their size does not exceed 3.5 cm. During their first 3-6 hours of life, they remain close to their father. After listening to the father's parting words, the young rag-pickers set off on their own to shallow water.

The view is taken under state protection. Rag-pickers in Australia are bred in aquariums and sold for export. In captivity at good care they live up to 10 years.

The grassy sea dragon belongs to the needle family (Syngnathidae), which combines seahorses and sea ​​needles. Everyone has known about seahorses for a long time and are already accustomed to their bizarre appearance, but here we have something really unusual!

Let's face it, seahorses don't look all that similar to the animals they're named after. Firstly, they have no hooves, and secondly, have you ever seen a horse with such a prehensile tail. The name "horse" these fish received mainly due to the shape of the head, well, or because they like to eat refined sugar. The last fact is at least unknown to me.

But the grassy sea dragon (Phyllopteryx taeniolatus), which will be discussed, fully justifies its name, except that it does not breathe fire.

Growing to a size of 45cm, these amazing imitators really do look like little dragons. Them dorsal fins look like wings. The image is complemented by armor on the body made of bone plates, a long tail and a head with a comb.

Such an unusual body structure is explained by the habitat. Grass sea dragon lives in temperate zone off the coast of South Australia among kelp and other marine plants. In these swaying forests they hide, hunting for mysid crayfish and other small marine crustaceans.

The rag-pickers lack a tail fin, so they are poor swimmers. These unusual creatures thanks to the vigorous strokes of the dorsal and pectoral fins. Fish form pairs for procreation in early summer, performing skillful mating dances. After that, the female lays up to 250 eggs, which stick to the tail of the male.

The role of the female in caring for offspring has been exhausted, and for the next couple of months, the male bears eggs on his tail until small copies of the parents hatch from it.

Unfortunately, there are many threats to this bizarre fish, mostly related to the destruction of natural habitats. Industrial mining rock lobsters leads to an increase in population sea ​​urchins Centrostephanus rogersii, which are preyed upon by lobsters. Sea urchin eats kelp and leaves grass sea ​​dragon on the open space, without food, defenseless against predators. Besides. Increases the chance of being washed ashore during a storm.

Deterioration of habitat conditions due to human activities - dredging, land reclamation, dumping Wastewater- further contributes to the extinction of the sea dragon. These and other factors have led Phyllopteryx taeniolatus to be introduced International Union nature conservation and natural resources, in the Red Book as endangered.

The seahorse is a small-sized fish that is a member of the Needle family from the order Sticklebacks. Studies have shown that the seahorse is a highly modified needlefish. Today, the seahorse is a fairly rare creature. In this article you will find a description and photo seahorse, you will learn a lot of new and interesting things about this extraordinary creation.

The seahorse looks very unusual and the shape of the body resembles a chess piece of a horse. The seahorse fish has many long bony spines and various leathery outgrowths on its body. Thanks to this body structure, the seahorse looks invisible among the algae and remains inaccessible to predators. The seahorse looks amazing, it has small fins, its eyes rotate independently of each other, and its tail is twisted into a spiral. The seahorse looks diverse, because it can change the color of its scales.

The seahorse looks small, its size depends on the species and varies from 4 to 25 cm. In the water, the seahorse swims vertically, unlike other fish. This is due to the fact that the swim bladder of a seahorse consists of an abdominal and a head part. The head bladder is larger than the abdominal one, which allows the seahorse to maintain an upright position when swimming.

Now the seahorse is becoming less and less common and is on the verge of extinction due to the rapid decline in numbers. There are many reasons for the extinction of the seahorse. The main one is the destruction by man of both the fish itself and its habitats. Off the coast of Australia, Thailand, Malaysia and the Philippines, skates are massively caught. The exotic appearance and bizarre body shape caused people to start making gift souvenirs from them. For beauty, they artificially bend their tail and give the body the shape of the letter "S", but in nature the skates do not look like that.

Another reason that contributes to the decline in the population of seahorses is that they are a delicacy. Gourmets highly appreciate the taste of these fish, especially the eyes and liver of seahorses. In a restaurant, the cost of one serving of such a dish costs $ 800.

In total, there are about 50 species of seahorses, 30 of which are already listed in the Red Book. Fortunately, seahorses are very prolific and can produce over a thousand fry at one time, which keeps the seahorses from disappearing. Seahorses are bred in captivity, but this fish is very whimsical to keep. One of the most extravagant seahorses is the rag-picker seahorse, which you can see in the photo below.

The seahorse lives in tropical and subtropical seas. Seahorse fish lives mainly at shallow depths or near the coast and leads a sedentary lifestyle. The seahorse lives in dense thickets of algae and other marine vegetation. It attaches with its flexible tail to plant stems or corals, remaining almost invisible due to its body covered with various outgrowths and spikes.

The seahorse fish changes body color to blend in completely with environment. Thus, the seahorse successfully disguises itself not only from predators, but also during food production. The seahorse is very bony, so few people want to eat it. The main hunter of the seahorse is a large land crab. The seahorse can travel long distances. To do this, he attaches his tail to the fins. various fish and rests on them until the "free taxi" swims into the algae thickets.

What do seahorses eat?

Seahorses eat crustaceans and shrimps. Seahorses are very interesting eaters. The tubular stigma, like a pipette, draws prey into the mouth along with water. Seahorses eat quite a lot and hunt almost the whole day, taking short breaks for a couple of hours.

During the day, seahorses eat about 3 thousand planktonic crustaceans. But seahorses eat almost any food, as long as it does not exceed the size of the mouth. The seahorse fish is a hunter. With its flexible tail, the seahorse clings to algae and remains motionless until the prey is in the required proximity to the head. After that, the seahorse sucks in water along with food.

How do seahorses reproduce?

Seahorses breed quite in an unusual way because the male carries the fry. It is not uncommon for seahorses to have monogamous pairs. mating season Seahorses are an amazing sight. The couple, who are about to enter into a marriage union, are fastened with their tails and dance in the water. In the dance, the skates are pressed against each other, after which the male opens a special pocket in the abdominal region, into which the female throws eggs. In the future, the male bears offspring for a month.

Seahorses breed quite often and bring large offspring. A seahorse gives birth to one thousand or more fry at a time. Fry are born an absolute copy of adults, only very tiny. The babies that are born are left to their own devices. In nature, a seahorse lives for about 4-5 years.
