today’s science fact is about an animal/plant fusion: Elysia chlorotica!

E. chlorotica is a sea slug that literally sucks the chloroplasts out of algae and preserves them to use for photosynthesis. Once a baby slug ingests enough chloroplasts it can potentially never have to eat again, relying on the sun for its energy needs. Recent studies have found that the slug encodes and expresses plant genes encoding chlorophyll- the green pigment used in photosynthesis- which needs to be continuously replaced in chloroplasts.
