As is the case in all gymnosome pteropods, these sea angels lack a shell except during an early embryonic stage.

The small lateral wing-like flaps (parapoda) are used in a slow swimming mode. The foot is reduced to three small median lobes.

gollark: I see. This will do for now.
gollark: Okay. I don't see why I should support this instead of deantimemeticizing the antimemes.
gollark: That runs counter to *many* of our policies.
