VENUS'S GIRDLE (Cestum veneris): SPECIES ACCOUNTS
SEA WALNUT (Mnemiopsis leidyi): SPECIES ACCOUNTS

Comb jellies live in all of the oceans of the world.


Most comb jellies live in open ocean. Some live at the bottom.


Comb jellies eat animal plankton or microscopic animals drifting in water, other jellies, crustaceans, mollusks, and fish larvae. Crustaceans (krus-TAY-shuns) are water-dwelling animals that have jointed legs and a hard shell but no backbone. Mollusks (MAH-lusks) are animals with a soft, unsegmented body that may or may not have a shell. Larvae (LAR-vee) are animals in an early stage that must change form before becoming adults.

Some comb jellies are harmful to fish that are caught and sold for food.


Comb jellies are not threatened or endangered.

Comb jellies either actively seek their prey or wait in ambush for it. Their long tentacles have muscular cores and a covering that contains sticky cells. The tentacles trail through the water or are twirled about by vario…
