The Uakari monkey is a unique and fascinating primate. Found in the rainforests of South America, they are easily distinguished from other monkeys by their bright red faces. They are also the only monkey that feeds almost exclusively on fruit, which gives them their characteristic round belly. Here are some additional information about these interesting creatures: [1] Unlike other primates who have for palms and for feet, Uakaris only have nails on their forefingers. This is thought to help them grip branches securely as they swing from tree to tree. [2] Uakaris live in troops of up to 40 individuals led by a dominant male. The rest of the Monkey hierarchy is based on strength and size.
