Creature of the Day – Lettuce Sea Slug

The Latin name for the Lettuce Sea Slug is Elysia Crispata, a much nice sounding moniker. This tiny critter looks like a bunch of lettuce, thus the name. I always thought it was a nudibranch, but, in fact, it is a gastropod mollusk.

Lettuce Leaf Nudibranch

Elysia Crispata eat green algae, some being digested and some being stored in the parapodia (fleshy lettuce leaf like appendages).

While diving the site called Oil Slick Leap, in Bonaire, we come across a myriad of these creatures and find them fascinating each time. They move so slowly and elegantly.
