Morphology

plectognath + fish

This is a straightforward noun–noun combination: 'plectognath' denotes a specific type of marine fish (fused teeth, tough skin) and 'fish' simply marks its category, so the full meaning is directly derivable from its parts. Although the term is technical and rare, its semantics are compositional rather than idiomatic, so a learner who knows both constituents would understand it.

Etymology

The name plectognath fish may come from old Greek parts plecto ('bound' or 'woven') and gnath ('jaw') because these fish have their teeth stuck together into a hard beak. That's why the name points to their strong, beak-like mouth used to crush shells.
