Morphology

crinoid = Crinoidea (opaque) = crino + oid

The noun uses the same technical combining form and suffix; the referent is a specific biological taxon, not derivable by general learners from component meanings.

Etymology

Crinoid comes from the Greek krinon 'lily' plus -oid 'like', so the word means 'lily-like'. That fits the animal sense because these sea creatures look like flowers and are often called 'sea lilies' because of their feathery arms.
