I have included the down on the human body and the lanugo on the foetus as a rudimentary representation of a hairy coat.
Man comes into the world covered almost entirely with lanugo or short fine hair.
lanugo la·nu·go (lə-nōō'gō, -nyōō'-)n. pl. la·nu·gos The fine, soft hair that grows on a fetus and is present on a newborn. Also called lanugo hair.
