Habitat of the Jellyfish. The lion's mane jellyfish, also known as the giant jellyfish, arctic red jellyfish, or the hair jelly, is one of the largest known species of jellyfish. Aquarists generally keep a gentle flow of water in their rounded tanks to prevent the jellies from drifting into the glass and injuring themselves.

You can find them in every ocean on Earth. [10] The female jellyfish carries its fertilized eggs in its tentacle, where the eggs grow into larva. (That claim has its critics: 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. Jennifer Kennedy, M.S., is an environmental educator specializing in marine life. A lion's mane jellyfish sting usually results in pain and redness in the area of the sting. Like other jellyfish, lion's manes are capable of both sexual reproduction in the medusa stage and asexual reproduction in the polyp stage.
