Moon Jellies

Mellow your mood with our gorgeous moon jellies! These beauties are named for their translucent, moonlike circular bells lined with a delicate fringe that sweeps the water for prey. The food collects on a mucous layer on the edges of their bells and is stored in pouches until the oral arms pick it up and begin to digest it.

The coloration of moon jellies often changes depending on their diet. If the jellies feed extensively on crustaceans, they turn pink or lavender. An orange tint hints that they've been feeding on brine shrimp. You can see these jellies pulse in person in The Jellies Experience and our Open Sea exhibit.
