Chrysaora quinquecirrha (known as the Atlantic sea nettle or East Coast sea nettle)
Chrysaora quinquecirrha (known as the Atlantic…
Moon jellyfish, named for their translucent, moonlike circular bell. Moon jellies have a short, fine fringe (cilia) that sweeps food toward the mucous layer on the edge of the bell. Prey is stored in pouches until the oral arms pick it up and begin to digest it. Photographed at the Monterey Bay Aquarium.
Moon jellyfish (Aurelia labiata)
Sea nettles hunt by trailing tentacles and mouth-arms covered in stinging cells which paralyze and capture prey, moving them to the mouth where they can be digested. Photographed at the Monterey Bay Aquarium.
Sea nettles (Chrysaora fuscescens)
Purple-striped jellies mysteriously appear near the shores of Monterey in certain seasons. Young cancer crabs are often found clinging to these jellies, even inside the gut. The crab helps the jelly by eating parasitic amphipods. Photographed at the Monterey Bay Aquarium.
Purple-striped Jelly (Chrysaora colorata)
Several marine lakes in the Republic of Palau have been cut off from the sea for 10,000-15,000 years. The jellyfish (Mastigias species) in these lakes have evolved to become stingless. The jellyfish also host symbiotic algae which require sunlight to photosynthesize. In order to provide enough light for their algae, the jellyfish migrate across the lakes during the day, following the sun.
