Big-eyed amphipod

Big-eyed amphipods live in jellyfish, just under the bell. You find them the most in rhizostome jellyfish that have washed ashore, although they live in other species as well. Big-eyed amphipods live off of the mass of jellyfish eggs as well as the food consumed by the jellyfish itself. Sometimes, you see coastal birds picking at beached jellyfish, in search of big-eyed amphipod.

  • Distribution and habitat

    Because adult big-eyed amphipods live in under the bell the rhizostome jellyfish in particular and often in moon jellies, their habitat is the same as that of these jellyfish. It is unclear where the big-eyed amphipod larva live before maturing into an adult.
