Horned Sapsucker

Elysia cornigera

Horned Sapsucker

This little sea slug eats algae but keeps the captured chloroplasts working inside its own body, so it can feed on sunlight like a leaf. It grazes Caulerpa and other green algae in very shallow water, only a couple of metres down, and grows no bigger than a fingernail.
