An Old World fossorial, the Encyocratella olivacea (Tanzanian Black & Gold Baboon) can be defensive and tends to stay hidden waiting for the opportune time to pounce on its prey. When on display, this species is a mesmerizing ochre yellow with black femurs. Under the femurs are yellow highlights that resemble sleeve garters.
