While most sea slugs graze on seaweeds on the ocean floor, this species in unusual in being pelagic: living in the open ocean, clinging to floating brown algae like Sargassum. These animals have a very sticky mucus, allowing them to cling to algae and thus stay afloat. As a result of its habitat, Stylocheilus longicauda is distributed around the globe at warm latitudes. The long "silly-string" being released by this slug is its egg mass, full of developing babies. Sea hares are snails with a very reduced shell, hidden under a flap-like mantle.
