The fish seemed to be interested in the jellies, but I couldn’t be sure as to their exact intentions. The current was forcing the drifting jellies into a vertical wall of the offshore pinnacle, which sent many of the jellies bouncing off the granite, only to tumble down the slope in an uncontrollable manner. Tentacle over bell they pulsed to right themselves, with some more successful than others. It was at this point of vulnerability that the blue rockfish would swoop in and begin to take bites out of the jelly’s long, less-potent oral tentacles. These frilly tentacles have weaker stinging cells and are the site of initial digestion when jellies capture prey. Perhaps the rockfish are consuming not just the jelly (which is mostly water) but also whatever the jelly has caught. Either way, it’s clear that jellies are indeed a food source for complex animals like these long-lived rockfish. .
