Least Concern/Population Growing These jellyfish can be found in deep waters off the coast of Southern California, and are only brought in close to shore due to high winds. They were not given a name until 71 years after discovery, and are considered the largest of their kind. Their main diets consist of copepods, larval fish, fish eggs and other jellies. When they swim their tentacles glide behind them, allowing prey to get caught in the tentacles, after which the jelly will draw the prey to their oral arm to eat. The Black Sea Nettle is not considered as toxic as its relative the Atlantic Sea Nettle.



Fun Fact: The jellyfish have symbiotic relationships with both larval and juvenile crabs. The crabs will stay until they are ready to move onto bottom feeding. Larval and juvenile butterfish use these jellies as protection from other predators.
