Glaucus atlanticus, blue sea slug, is a small, blue sea slug, pelagic nudibranch. G. atlanticus has a single row of a homodont tooth along a thin radular ribbon. G. atlanticus preys on other larger pelagic organisms such as the venomous Physalia physalis (Portugese man o’ war), the violet snail Janthina janthina, and by-the-wind sailor Velella velella.
