📸: @jacintashackleton // Glaucus atlanticus sea slug, or blue dragon, is a pelagic nudibranch that sails on the surface of the ocean. They are typically just an inch long, and feed on the toxins of much larger species such as Portuguese man o’ wars, which have tentacles around 30 feet. The blue dragon is immune to the toxins, and collects them in special sacs within the finger-like branches at the end of its appendages. When threatened or touched, it can release stinging cells with more powerfu
