Seeing how much you liked our "Sea Bunny" and "Sea Sheep" post, we decided to dive deeper to see what else is hidden beneath the sea. We were pleasantly surprised to find that the ocean is full cute slugs!
Most of these “slugs” are actually snails that have lost their shells and gained new characteristics through evolution. For example, sacoglossans are sometimes called “solar-powered sea slugs” because they use chloroplasts from the algae they eat in their own tissue.
Vote for your favorite, or if you happen to be a deep-sea diver, post  your own pictures below!
