This sensory mechanism arose because the Protheans evolved as hunters and needed to be thoroughly aware of their environment. This system can transfer complex ideas, with a Prothean being capable of learning a new skill or foreign language with a single touch. By touching something or someone, a Prothean could recall its experiences. Prothean blood is red.Ī unique attribute of Prothean physiology is an experiential exchange system based on physical touch. Their hands each have three fingers, and their feet each have two widely-spaced toes. The skin surrounding this carapace can be a pale blue-gray or brown color mottled with muted yellow spots. Their heads are covered in a thick, layered carapace that gives them a distinctive shape. Their eyes have some ability to see through cloaked objects or entities. Much like turians, Protheans have a similar flanging effect in their voices.

They have two pairs of eyes with each eye possessing dual pupils, and three pairs of nostrils.
