The osteoderms are extremely vascularised and support in calcium balance, both equally to neutralize acids whilst the animal simply cannot breathe underwater[59] and to offer calcium for eggshell development.[60] Crocodilian tegument have pores considered to become sensory in perform, analogous to the lateral line in fishes.
