Morphology

order + Exocycloida

This is a compositional noun phrase: 'order' names a taxonomic rank and 'Exocycloida' is the taxon label, so the meaning ('the taxonomic order called Exocycloida') follows directly from the constituents. The structure reflects standard biological naming conventions (rank + name), which is cross-linguistically transparent and therefore predictable to learners who know both words.

Etymology

Order Exocycloida gets its name from Greek word parts used by scientists: exo- meaning 'outside', cyclo- meaning 'circle', and -oida meaning 'like'. This creates a simple image of the animals in the group — flat, round sea urchins — so the name points to their shape.
