thingiverse

Glaucus atlanticus is known by several common names, including blue angel, blue glaucus, blue dragon, blue sea slug, and blue ocean slug. This species of small sea slugs is a pelagic aeolid nudibranch that belongs to the family Glaucidae, comprising shell-less gastropod mollusks. These sea creatures are uniquely adapted to float upside down at the water's surface, where they ride the winds and ocean currents. Their body coloration plays a crucial role in this adaptation, with the blue side facing upwards and blending seamlessly into the surrounding water. The silver/grey underside faces downwards, mirroring the silvery hue of the sea. Glaucus atlanticus is a formidable predator that feeds on other pelagic creatures, including the venomous siphonophore, also known as the Portuguese man o' war. This sea slug has a remarkable defense mechanism, storing stinging nematocysts from its cnidarian prey within its own tissues. As a result, humans handling these slugs may receive severe and potentially hazardous stings.
