angler fish belongs to the suborder tseratsievidnyh (Ceratioidei), detachment Lophiiformes, comprising more than 100 species.It lives in the ocean, it is thicker at depths of 1.5 to 3 km.Her body was spherical, flattened on the sides.The head is huge, occupying more than half of the total length.Mouth frightening, with long, sharp teeth.Bare skin is a dark color, spines and plaques characteristic only for some species."Rod," which gave the name of the squad - is to modify the first ray of the fin located on the back.He is only in females.
was felt that ugly shape with bulging eyes is fish angler.Photo shows it after lifting with depth.In a typical environment, it looks completely different.We estimate the impact huge pressure difference (250 atmospheres) in the water and on the surface.
Deep angler - the creation of amazing.Females are larger than men's for a hundred times.Females, which are able to catch and remove from the sea water, found themselves in the range of 5 to 100 cm in length, and the males - from 1.6 to 5 cm. This is one of the manifestations of sexual dimorphism.The second is illitsy in common - Rod females.It is worth noting that it ends with a glowing bioluminescent bacteria by "bait."Fish angler is able to "turn on and off" him by narrowing the blood vessels that feed a kind of iron in blood.Length illitsiya different in different species.For some it can be extended and reduced, luring a victim straight into the jaws of the hunter.
amazing and the food of these fish.Females feed on deep-sea fish, crustaceans, mollusks occasionally.Their stomach can increase in size at times.There are cases when they are victims of many of the largest swallowed itself.This greed led to the death, becausefemale choked "dinner" and release it from itself could not long teeth detained.Male, given the small size available copepods and chaetognaths.
Some species anglers inherent parasitism of males.This is manifested in the fact that a male to find a female on pheromones, teeth seizes it, and can not disconnect.Over time, his jaw, teeth, intestines, eyes lose the need to function, although a meeting with her, he was a full body.Their blood vessels grow together, and the result is a male in a female appendage, but the ability to produce sperm.Sometimes, one a female can parasitize several men.
angler fish breed in the spring and summer.Females spawn small eggs, the males fertilize them.With the depth of the eggs float to the surface layer (up to 200 m), where there are more opportunities to feed themselves.Here and there the larvae.By the time of metamorphosis fingerlings descend to a depth of 1 km.After the transformation of fish angler will take on an even greater depth, which reaches sexual maturity and intrinsic live her life.
angler fish - one of the manifestations of the diversity of the natural world.Apparent to us miraculously existence by chance elaborated centuries.Much remains unknown.Perhaps someday an explanation will be found.
