Morphology

jawless = jaw (transparent) = jaw + less

The adjective is a regular formation from the noun 'jaw' plus the productive suffix '-less' meaning 'without', so the meaning is directly deducible.

Etymology

Jawless combines jaw and the ending -less, which means 'without', just like in hopeless. So jawless describes an animal 'without a jaw', for example the lamprey or hagfish.
