Cinder - one of the inhabitants of the St. Louis Zoo. At birth in 1994, she was a normal chimpanzee until within a few months she has not lost all his hair.

Unlike people suffering from hair loss, Cinder not threaten the social and psychological effects of hair loss, so it is no different from the behavior of their brothers and sisters.
