Morphology

nonprotractile = protractile (semi-transparent) = non + protractile

Formation is a regular negation (non- + protractile) where 'non-' straightforwardly negates the adjective 'protractile'.

Etymology

Nonprotractile breaks into non- 'not', pro- 'forward', and tract 'to pull', the same root you see in tractor. So a nonprotractile body part is 'not able to be pulled forward', which is why it cannot be extended or pushed out.
