West Coast sea nettle, Monterey Bay Aquarium.
A common variety of true jellyfish found in the Pacific Ocean (mostly near the coast from California to Alaska). Not all jellies sting, but the West Coast sea nettle packs a powerful punch. The "bell" can grow up to 3 feet and the long and the spiraling oral arms accompanied with the 24 stinging tentacles may trail as far as 12 to 15 feet long. It hunts tiny drifting animals by trailing those long tentacles and frilly mouth-arms in the current.
