[edit] Distribution
This species is pelagic, and like many other pelagic species, it can be found worldwide.
[edit] Habitat
These small nudibranchs float upside down on the surface tension in temperate and tropical seas.
[edit] 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.
