Morphology

Crinoidea = crinoid (opaque) = crino + idea

The form is a scientific/taxonomic formation using the combining form 'crino-' and the taxonomic suffix '-idea', which is not a productive or transparent derivation for average learners.

Etymology

Crinoidea comes from Greek krinon meaning 'lily' and the ending -oidea meaning 'like' or 'in the shape of'. These animals are often called 'sea lilies' or feather stars because their cup-like bodies and feathery arms look like a flower, so the name describes how they appear.
