Morphology

phylum + Echinodermata

This is a fully compositional technical noun phrase: 'phylum' (a taxonomic rank) combined with the proper taxon name 'Echinodermata' denotes exactly the taxonomic group. A learner who knows both constituents can directly infer it refers to the phylum comprising radially symmetrical marine invertebrates; taxonomic naming is cross-linguistically similar and follows predictable composition.

Etymology

The name phylum Echinodermata comes from Greek words echino ('spiny') and dermata ('skin'), so it literally means 'spiny skin'. Think 'spiny skin' to remember animals like starfish, sea urchins and sea cucumbers that have hard, bumpy bodies.
