"Glaucilla marginata" is a species of small, floating, blue sea slug; a pelagic aolid nudibranch; a marine opisthobranch gastropod mollusk in the family Glaucidae.

Distribution

This species is pelagic, and like many other pelagic species, it can be found worldwide.

Habitat

These small nudibranchs float upside down on the surface tension in temperate and tropical seas.

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, while in "Glaucilla" there are multiple rows.
