Forms: 1800s crinoïd, 1800s– crinoid.

Origin: A borrowing from Greek, combined with an English element; modelled on a Latin lexical item. Etymons: Greek κρίνον , -oid suffix.

Etymology: < ancient Greek κρίνον lily (see crinum n.) + -oid suffix, after scientific Latin Crinoidea (or Crinoida), class name ( J. S. Miller Nat. Hist. of Crinoidea (1821)). Compare Hellenistic Greek κρινοειδής lily-like.

Zoology and Palaeontology.

A. adj.

Of, relating to, or characterized by echinoderms of the class Crinoidea, which have a small disc-like body with long feathery arms for feeding, and either a segmented stem attached to the substrate (in sea lilies) or short appendages for grasping the substrate (in feather stars). Cf. crinoidal adj. at Derivatives.The crinoids are abundant as fossils in Palaeozoic deposits but are now much reduced in both numbers and variety.
