Common Moon Jelly
Aurelia auritaAlso known as Moon Jellyfish, Saucer Jelly, Common Jellyfish
Moon jellies drift gracefully through temperate coastal waters, propelling themselves with rhythmic pulsing of their saucer-shaped translucent bells. Four distinctive violet or pink horseshoe-shaped gonads visible through the translucent bell reveal their reproductive maturity to observers from above. Although drifting largely with ocean currents, tiny stinging tentacles fringe the bell edge to sweep up zooplankton.
