South American Sea Nettle

As with most other jellies, the tentacles on this jelly have small, barbed stingers called nematocysts that release a toxin to immobilize their prey. They feed on zooplankton, larval fishes, and even other jellies. The bell of this jelly can grow up to around twelve inches or more in diameter and six feet or more in length. They can have different color variations from white with a brown tint to orange. You may sometimes see small crustaceans and juvenile fish on them, which use this jelly for shelter and protection.
