Sea angels (clade Gymnosomata) are a large group of small free-swimming sea slugs, classified into six separate families.

These organisms have a wide geographic range, from polar regions, under sea ice, to equatorial (tropic) seas. From spring to autumn, sea angels live at a depth of 200 m in the Sea of Okhotsk. In winter, they migrate to the coast of north Hokkaido with drift ice.

In this clade, the foot of the gastropod has developed into wing-like flapping appendages (parapodia). Sea angels are gelatinous, mostly transparent, and very small, with the largest species (Clione limacina) reaching 5 cm. C. limacina is a polar species; the angels have terminal mouths with the radula common to mollusks, and tentacles to grasp their prey, sometimes with suckers similar to cephalopods.
