The Caulerpa Elysia has a body that ranges from green to yellow, tan, or red. It has small white bumps and a thin brown line along the edge of its ruffled flaps. The head has a white patch that reaches the short rhinophores. Its appearance can vary widely between individuals.

This Elysia feeds on green algae such as Penicillus and Udotea. It lives on rocks and algae and often blends in with its surroundings because of its color variation. It moves slowly along the bottom.
