Some Elysia species are found in the Florida Keys. Elysia clarki (pictured on the left) is typically found inshore, whereas Elysia crispata (pictured on the right) is found on reefs.

Both E. clarki and E. crispata retain living chloroplasts that continue to photosynthesize within the body of the sea slug, providing sugars for its nutrition. They have become "solar powered." The process of taking chloroplasts from algal cells and storing them is called kleptoplasty.

FWC Facts:
Panthers space themselves so they will have enough food. If panthers lived close together, all the deer would soon be gone, and there wouldn't be enough to eat.
