Pacific Sea Nettles – Monterey Bay Aquarium, Monterey, California

Not all jellies sting, but the sea nettle does. It hunts tiny drifting animals by trailing its long tentacles and frilly mouth-arms, all covered with stinging cells. When the tentacles touch prey, the stinging cells paralyze it and stick tight. From there, the prey is moved to the mouth-arms and finally to the mouth, where it’s digested.
