Giant jellyfish tsianeya: description, lifestyle, interesting facts

no secret that in every group of vertebrates (type, class, family, genus) found their champions for various achievements.Not far behind them and invertebrates, because among them there are also those who are to be envied!One of these creatures - giant jellyfish tsianeya.

Giant sea

lion's mane jellyfish - the largest jellyfish in the world.This is a true giant of the seas and oceans.Full name it - Cuanea arctica, which translated from Latin sounds like "Jellyfish Arctic tsianeya."It's beautiful luminous pink-purple creature can be found in the high latitudes of the Northern Hemisphere: jellyfish is common in all the northern seas, flowing into the Pacific and Atlantic Oceans.You can see it directly near the coast, in the upper layers of water.Researchers who have studied the hairy cyan, initially looking for her in the Azov and Black seas, but never found.

Medusa tsianeya.The impressive size

The latest oceanographic research, which lead the expedition so-called Cousteau team, the diameter of t

he gelatinous "body" (or dome) cyanogen can be up to 2.5 m. But that's what!Subject pride hairy Arctic jellyfish - is its tentacles.The length of these processes varies from 26 to 42 m!Scientists came to the conclusion that the size of these jellyfish entirely depend on the conditions of their habitat.According to statistics, the huge size of it have individuals who inhabit the most cold ocean waters.

external structure

hairy jellyfish tsianeya has quite a variety of colors of the body.It is dominated by brown, purple and red tones.When it becomes an adult jellyfish, its dome ('body') is clearly on top begins to turn yellow, and the edges - blush.The tentacles are located at the edges of the dome are violet-pink hue, and oral lobes - the red and crimson.It is because of the long tentacles cyan and called hairy (or hairy) jellyfish.The dome itself, or bell, cyan Arctic has a hemispherical structure.Its edges are smoothly into the blades 16, which, in turn, separated from each other by specific cutouts.

Lifestyle

lion's share of its numerous times these beings is carried out in the so-called free-floating - floating on the surface of sea water, periodically reducing its gelatinous dome and extreme flapping blades.Hairy tsianeya - is a predator, and very active.It feeds on plankton, floating in the surface layers of water, shellfish animals and medium-sized fish.In a particularly "hungry years", when there is literally nothing to tsianeya may be a lot of hungry.But in some cases, these beings become cannibals, devouring their own relatives.

Cousteau team members describe their research method of hunting that uses jellyfish.Hairy tsianeya rises to the surface of water, stroking his very long tentacles in all directions.She waits for his victim.The researchers noticed that in that state tsianeya very much like seaweed.Should the victim to swim to close this "algae" and touch them as jellyfish immediately encircled their prey, releasing it using the so-called poison stinging cells that can paralyze.Once production ceases to show signs of life, it eats jellyfish.The venom from this giant gelatinous strong enough and produced over the entire length of the tentacles.

Reproduction

Propagated is to create a very unusual way.Male through the mouth throws his sperm into the female's mouth.Strictly speaking, that's all.It was in the mouth of the female jellyfish nucleation occurs.When the "kids" will grow up, they will come out in the form of larvae.These larvae, in turn, attach to the substrate, turning into a single polyp.A few months later the grown polyp begins to multiply, after which the larvae will have future jellyfish.

Interesting facts

Until now, the largest caught Arctic tsianeey, officially registered in the documents is the creation, in 1870, thrown out on the Gulf Coast in the US state of Massachusetts.The diameter of the dome of this giant was 2.3 m, and the length of the tentacles - 36.5 m. At present, scientists do know about the existence of copies of the gelatinous body with a diameter of 2.5 m and a length of 42 m tentacles. These jellyfish have been recorded usingscientific underwater submersibles within oceanographic expeditions, but to catch at least one such individual until now no one has succeeded.

Medusa tsianeya known among divers their painful burns.Officially the world's largest jellyfish is considered dangerous to humans.But the fact was recorded only one death.Typically, this leaves a burn on human skin local redness, which extends for some time.Sometimes a rash appears on the body, accompanied by painful sensations.And all because the venom contains a giant in its composition toxins that can cause an allergic reaction.However, if you are stung by a giant jellyfish tsianeya, it is recommended to consult a doctor.
