Morphology

order + Anaspida

The phrase is directly compositional: 'order' as a taxonomic rank combined with 'Anaspida' (a group of prehistoric fishes) yields the meaning 'the taxonomic order comprising Anaspida'. This follows standard biological naming patterns found cross-linguistically, so a B1 learner who knows both constituents can readily infer the MWE's meaning.

Etymology

Order Anaspida is a scientific name from old Greek: the parts an- and aspida mean 'without shield'. Early fossils showed these animals had no heavy head armor and a smooth body, so the name fits this extinct group of jawless, fish-like animals.
