Get an up-close look at the delicate sea nettles in our Open Sea exhibit.

Watch our sea nettles as their long tentacles and lacey mouth-arms move smoothly through the water. But don't let these unassuming invertebrates fool you — their graceful trailing parts are covered in stinging cells used for hunting. When their tentacles touch tiny drifting prey, the stinging cells paralyze it and stick tight. The prey is moved to the mouth-arms and then to the mouth, where it's digested.

These Crystals Can Clear Your Head, Too

Crystal jellies are very transparent about their life in the open ocean. The frilly mouth of the jelly — the little clapper below the bell — moves along the edge of the bell to slurp food from the tentacles. Radial canals — the spoke-like structures — move nutrients about the jelly. It's crystal clear these jellies are awesome!

Join Us for Our Jellies and Open Sea Tour

A fish as big as a car glides past, while thousands of sardines move as one. Nearby, jellies shimmer and pulse. This exhibit gives the impression of an infinite ocean, and will expand your view in the same way. Go deep with our guides as they highlight their favorite spots — plus a few sneak peeks behind the scenes.

Cracking the Comb Jelly Code!

Our innovative aquarists cracked the code to raising beautiful, rainbow-generating comb jellies behind the scenes. You can see several members of this shimmering species on display in our Open Sea exhibit.
