SERPENTINE SEA NEEDLE
Serpentine sea needle — one of the most common representatives of the family needle. Uncanny ability to blend in with the environment makes it almost invisible in the water.
Serpentine sea needle lives in shallow coastal waters, holding, usually at a depth of from 2 to 15 meters and Found that fish in the Atlantic ocean from the southern coast of Norway to the northwestern coast of Africa and the Mediterranean, Black and Baltic seas. Quite often it can be found in the brackish waters of river estuaries.
DID YOU KNOW?
To maintain the vertical position of the sea needle help gases accumulated in its swimming bladder.
Serpentine sea needle is able to suck in the mouth the prey from a distance of 3-4 cm.
The most rich in species needle fish tropical sea. Many species have camouflage coloring, but some wear very bright outfits.
Having tight, inflexible body and only one dorsal fin, serpentine sea needle floats is very bad. Long swims fish are not capable of, and stay in the open sea is simply disastrous.
The pipefish eggs are only 1 mm in diameter.
Males of all needle fish are carrying eggs in brood pouches formed by the lateral folds of the skin. Stretching along the abdomen of the fish globalperspective caviar inflow of fresh water. In some species skin folds are rolled inward, hiding the eggs, or form a pocket that isolates the seed from the external environment. The embryos receive oxygen through the inner wall of a marsupial pouch, densely penetrated by blood vessels.
The sea needle is easier to see when it appears jj£ on a sandy bottom, leaving shelter among the algae.
Serpentine sea needle leads a sedentary life, hiding from prying eyes in the thick underwater vegetation. Most often it rests among algae in vertical position. The prehensile end of his long fish tail wraps around the plant stem and long standing as if at anchor, adjusting the position of the body barely noticeable movements of the dorsal fin. In many places pipefish live in close-knit flocks, preying on small crustaceans and the fry of other fish. During feeding, sea needle hang in the water vertically by turning the head against the tide and patiently waiting for the appearance of some planktonic crustacean. To monitor what is happening around her help her ability to move independently from each other. Barely prey to come close enough, the bones of the Gill covers of fish apart, and a tubular snout like a pipette, sucks the prey into the mouth. Due to the excellent disguise pipefish rarely catch the eye of enemies, but often suffer from storms, which tear these fish with anchor and carry away from the coast. After the storm pipefish trying to get back to shallow water, but they swim poorly, with difficulty coordinating movements. Only a few manage to come back, and most fall victim to predators.
The spawning of the serpentine sea-eagle occurs from may to August. The initiator of the mating ritual, the female stands. After the stately dance of courtship partners turn their heads to each other and entwined bodies. With the help of ovipositor of female small portions places the eggs in a brood pouch bag male. Sprouses during the season with multiple partners, the female lays 200 to 300 eggs. Each male carries from 50 to 200 eggs; along the abdomen it reaches the groove formed by the folds of the skin, and the fertilized eggs are attached in two rows to the side walls. After three weeks of them produce larvae with a length of about 9 mm, equipped with pectoral and tail fins. Within 3-4 months the larvae lead a pelagic life, floating freely in the water and pee
openly plankton. During this time they disappear pectoral and caudal fins, and by the end of this process the youngster settles in the midst of plants to start adult life. Puberty young fish reach one year old.
During the spawning season on the Gill covers and at the front of the body females have a blue stripes on the abdomen – a broad yellow spot.
Fish collection needle feature narrow, elongated into a tube snout and long, narrow body. The males of many species of this family on the belly there are special bags in which hatched the eggs and larvae hide. Scaly needle cover do not: the body of these fish are protected by armor, consisting of a number of bone links. Most often needle settle in underwater thickets, where it’s easy to find refuge from predators.
Ordinary sea needle (Syngnathus acus) is small and the pectoral fins are quite tiny anal fin. Inhabits the North Atlantic and the North sea.
Large serpentine needle-fish (Entelurus aequoreus) in length reaches up to 60 cm is Found in the North Atlantic, near the coast of Western Europe and the Scandinavian Peninsula.
