The osteoderms are remarkably vascularised and assist in calcium equilibrium, both of those to neutralize acids though the animal can't breathe underwater[59] and to provide calcium for eggshell formation.[sixty] Crocodilian tegument have pores considered being sensory in functionality, analogous to your lateral line in fishes.
