Morphology

jawless + vertebrate

The meaning is directly compositional: 'jawless' (without jaws) modifies 'vertebrate' (a backboned animal), so a B1 learner who knows both constituents can easily infer 'a vertebrate without jaws.' This adjective+noun pattern is a regular, cross-linguistically common construction, making the expression transparently interpretable.

Etymology

Jawless vertebrate is a name that gives a simple picture: jawless means 'no jaws' and vertebrate means an animal with a 'backbone'. Think of lampreys or hagfish, long eel-like animals with round, sucking mouths. That's why the term means an eel-shaped animal with a backbone but without jaws or paired fins.
