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.

Meet Our Newest Odd Couple
