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.

Distribution

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

Habitat

These small nudibranchs float upside down on the surface tension in temperate and tropical seas. They eat colonial cnidarians such as the Portuguese Man of War.[2]

Description

This nudibranch is dark blue, and in many ways it resembles a smaller version of Glaucus atlanticus. However, in this species the cerata (saw teeth on the skin) are arranged in a single row in each arch.
