A few minutes of pelagic magic with wild sea nettle jellyfish, filmed just off the back deck of the Aquarium, for your littoral relaxocean needs! • More Littoral Relaxocean: • 20 Minutes of Bioluminescent Waves + ... • We filmed this video a few weeks ago along Cannery Row, just off the back deck of the Aquarium! These jellies are Pacific sea nettles, Chrysaora fuscescens—the same ones you may have seen on our Jelly Cam! ( • Live Jelly Cam - Monterey Bay Aquarium ) • Sea nettles are very seasonal here in Monterey Bay, usually showing up in mid to late summer, and sometimes in massive numbers that turn the water very spicy. • Sea nettles are plankton, meaning that they drift with ocean currents. “Plankton” isn’t a size thing, it’s a lifestyle. If you’ve got friends drifting through life with no real direction, then you know a plankter or two. Sea nettles are also planktivores, meaning they eat drifting critters, like tiny shrimps and larval fishes and other jellies. • Lots of animals are planktivores, and many animals eat sea nettles, from sunfish to sea turtles and even the blue rockfish in this video at 1:20—with one even thinking about enjoying a jelly donut for a second there! • Sea nettles are a type of jellyfish known as a scyphozoan, or “bell animal.” The top part here is the bell, housing the famous jelly of the jellyfish. Scientists call this the mesoglea, or “middle jelly”, because it's sandwiched between two layers of skin, the orange epidermis (outside skin) and the clearer gastrodermis, or stomach-skin. The frilly folds of gastrodermis behind those red stinging tentacles are the jelly’s mouth arms—essentially long lips that slurp up plankton soup as the jelly swims. (Heads up that jellies don't actually have skin like us, as they only have tissues and not organs.) • Watching jellies swim is simply mesmerizing—and there’s a lot going on with each ring of a jelly’s bell. Muscles contract against the mesoglea, accelerating the pulse to the thin edges of the bell like a whip, creating water currents that pull food toward the jelly’s mouth arms! A swimming jelly isn’t really trying to go anywhere, so much as it’s vacuuming up planktonic pieces of pie with every blobby scull—like if a lava lamp joined forces with a roomba. • There were some huuuuge sea nettles that day—the one at 2:03 had a bell almost two feet across! These open ocean beasts often show some wear and tear on their bells, battle scars from their long voyage through the inner space of planet ocean. • At the end of the video you'll find a northern kelp crab, Pugettia producta, hanging out in the giant kelp, watching current events go by… Solid plan if you’re feeling crabby. • On the way back to the Aquarium, little blubber bud came by to say hey—harbor seals are like curious cats in the kelp forest, sea lions are much more the “ocean doggos” you’ve heard about on the Internet. Ah yes, and then a few senorita cleaner wrasses came by to see if we needed any help tidying up the end of this video—thanks for the kelp! • We hope you enjoyed this dive in the Monterey Bay!
