Differential ingestion and digestion of bivalve larvae by the scyphozoan Chrysaora
quinquecirrha and the ctenophore Mnemiopsis leidyi.
Dense aggregations of jellyfish (Scyphomedusae), primarily Chrysaora
Brodeur (1998) observed juveniles swimming near the bells of scyphomedusae Cyanea capillata and Chrysaora
melanaster and retreating behind the tentacles or within the bells of these jellyfish when approached by a remotely operated vehicle, apparently as a means of protection from predators.
More precisely, it is a Pacific sea nettle, Chrysaora
melanaster, floating in the undifferentiated murk of the Long Beach, California, aquarium, a place one goes to see such things.
