Lion’s Mane Jellyfish (Cyanea capillata)

Hi, aftere of all the work than i am doing today , here have another blog this turn is about the fourth most dangerous( Lion´s Mane Jellyfish) jellyfish in the world . So here we go!

The lion's mane jellyfish (Cyanea capillata), also known as the giant jellyfish or the hair jelly,is the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans. It is common in the English Channel, Irish Sea, North Sea and in western Scandinavian waters south to Kattegat and Øresund. It may also drift in to the south-western part of the Baltic Sea (where it cannot breed due to the low salinity). Similar jellyfish – which may be the same species – are known to inhabit seas near Australia and New Zealand. The largest recorded specimen found, washed up on the shore of Massachusetts Bay in 1870, had a bell with a diameter of 2.3 metres (7 ft 6 in) and tentacles 37.0 m (121.4 ft) long. Lion's mane jellyfish have been observed below 42°N latitude for some time in the larger bays of the east coast of the United States.

The lion's mane jellyfish uses its stinging tentacles to capture, pull in and eat prey such as fish, sea creatures and smaller jellyfish.

Lion's mane jellyfish (Cyanea capillata) are named for their showy, trailing tentacles reminiscent of a lion's mane. They can vary greatly in size: although capable of attaining a bell diameter of over 2 metres (6 ft 7 in), those found in lower latitudes are much smaller than their far northern counterparts, with a bell about 50 centimetres (20 in) in diameter.

Size seems to dictate coloration: larger specimens are a vivid crimson to dark purple while smaller specimens grade to a lighter orange or tan, occasionally colorless.

The bell of the lion's mane jellyfish is scalloped into eight lobes (lappets), each lobe containing from 70 to 150 tentacles,arranged in four fairly distinct rows. Along the bell margin is a balance organ at each of the eight indentations between the lobes – the rhopalium – which helps the jellyfish orient itself. From the central mouth extend broad frilly oral arms with many stinging cells.

The long, thin tentacles which emanate from the bell's subumbrella have been characterised as “extremely sticky”; they also have stinging cells. The tentacles of larger specimens may trail as long as 30 m (100 ft) or more, with the tentacles of the longest known specimen measured at 37 m (120 ft) in length. This unusual length – longer than a blue whale – has earned it the status of one of the longest known animals in the world.
