Seajelly Cam

You are looking at the magnificent west coast sea nettles in the Aquarium of the Pacific in Long Beach. West coast sea nettles are a type of jelly, an invertebrate made up mostly of water. Jellies have no heart, brain or bones. They swim by jet propulsion; by expanding then quickly contracting, water is forced away from its bell-shaped body, pushing the jelly in the opposite direction. The aquarium has successfully cultured this species for many years and often shares the jellies with other aquariums. It takes about three months to rear the jellies from polyps to ephyrae, the adult stage.
