Translation of "Exoskeleton" in French

Scorpions have this thin layer that coats their exoskeleton,

L'exosquelette du scorpion est recouvert d'une couche fine

That's a hairy desert scorpion, and look how that whole exoskeleton just lights up.

C'est un Hadrurus. Et regardez… comme son exosquelette s'illumine.
