Morphology

Plectognathi = plecto + gnath + i

The term is a Latin/Greek scientific compound (combining forms plus a Latin plural ending) and its parts are not productive or readily interpretable by average learners, so the meaning is not derivable from the components.

Etymology

Plectognathi comes from Greek parts plecto- meaning 'twisted' or 'woven' and -gnath meaning 'jaw'. A helpful image is that these fishes have jaws that are almost 'tied together', which explains their fused jaws and hard, often box-like bodies.
