Glaucus marginatus is a species of small, floating, blue sea slug; a pelagic aeolid nudibranch; a marine opisthobranch gastropod mollusk in the family Glaucidae.[1][2] 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.[3]

Distribution[edit]

This species is pelagic, and can be found in the Pacific Ocean.

Habitat[edit]

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.[2]

Description[edit]

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.
