Glaucus marginatus is a species of small, floating, blue sea slug; a pelagic aeolid nudibranch; a marine opisthobranch gastropod mollusc in the family Glaucidae. This species is closely related to Glaucus atlanticus, and is part of a species complex (Informal clade Marginatus) along with Glaucus bennettae, Glaucus thompsoni, and Glaucus mcfarlanei.
This species is pelagic, and can be found in the Pacific Ocean.
These small nudibranchs float upside down on the surface tension in temperate and tropical seas. They eat colonial cnidarians such as the Portuguese man o' war.
This nudibranch is dark blue, and in many ways it resembles a smaller version of Glaucus atlanticus. However, in this species the cerata are arranged in a single row in each arch.
