green slug

 
Elysia chlorotica. This little gem is indigenous to the salt marshes of New England and Canada. What makes this slug so special is that it is member of both the flora and fauna kingdoms. It claims this hybrid state by producing it’s own chlorophyll, thereby gaining energy from the sun’s rays. All the baby slug needs to do is have it’s first and only meal of algae to steal some chloroplasts and from then on it’s a life of sunbathing.
