while on a camping trip my my sister and some friend found a large jellyfish the size of my head it was one of the best things i ever saw and it comen for jellyfish to wash up in that area so i decide to do a little research on it..
Although capable of attaining a bell diameter of 2.5 m (8 feet), these jellyfish can greatly vary in size, those found in lower latitudes are much smaller than their far northern counterparts with bells about 50 cm (20 inches) in diameter. The tentacles of larger specimens may trail as long as 30 m (90 feet) or more. These extremely sticky tentacles are grouped into eight clusters, each cluster containing over 100 tentacles,[5] arranged in a series of rows.
At 120 feet in length, the largest known specimen was longer than a Blue Whale and is generally considered the longest known animal in the world.[6][7][8] However, in 1864, a Bootlace worm was found washed up on a Scottish shore that was 180 feet long. But because bootlace worms can easily stretch to several times their natural length, it is possible the worm did not actually grow to be that length.
The bell is divided into eight lobes, giving it the appearance of an eight-pointed star. An ostentatiously tangled arrangement of colorful arms emanates from the centre of the bell, much shorter than the silvery, thin tentacles which emanate from the bell's subumbrella.
Size also dictates coloration—larger specimens are a vivid crimson to dark purple while smaller specimens grade to a lighter orange or tan. These jellyfish are understandably named for their showy, trailing tentacles reminiscent of a lion's mane.
On July 21, 2010, 50 to 100 people are thought to have been stung by the remains of a dead Lion's mane jellyfish that had broken up into countless pieces in Rye, New Hampshire in the United States. Considering the size of the species, it is possible but not likely that this mass incident was caused by a single specimen.[13]
