Morphology

Gnathostomata = gnathostome (opaque) = gnath + stoma + ata

The relation gnathostome -> Gnathostomata is a regular taxonomic pluralization, but the base 'gnathostome' is a specialist term built from Greek combining forms that many learners will not recognise.

Etymology

Gnathostomata comes from Greek parts gnath- meaning 'jaw' and -stoma meaning 'mouth'. So Gnathostomata names the group of animals that have both upper and lower jaws and a mouth, like most fish, amphibians, reptiles, birds, and mammals.
