Chiridotidae is a family of sea cucumbers.

Description and characteristics

Members of this family have 10, 12, or 18 pelto-digitate tentacles (bearing 3-10 digits on each side). They lack podia, radial canals and respiratory tree.

The soft body wall is supported by ossicles which are generally wheel-shaped with six spokes.[1] Some species have hook-shaped or rod-shaped ossicles or spiny sigmoid bodies.[2]

gollark: The obvious explanation is (anti)memetics.
gollark: So there's this thing which is irritating to produce, and a presumably comparatively easy way to make it available to the population of mages, and nobody ever thought "Hmm, maybe I could make lace and exchange goods and services for money"?
gollark: And there aren't mages around who can produce lace anyway? How inefficient.
gollark: Although really, knowing what sets are puts you ahead of the majority of the population.
gollark: This set is actually uncountably infinite.
