Most primates show erectness in the upper body and exhibit occasional bipedalism (Humans are erect and always exhibit bipedalism). They range in size from the 2-ounce pygmy mouse lemur to the 440-pound wild gorilla. All primates exhibit the tendency to be erect; this trait is visible when even quadrapedal primates sit or stand. Since all primates are descendent of tree-dwellers, they exhibit adaptive features which allow them to climb trees. The brains of primates often is one of the most distinguishable characteristics from other types of mammals or animals. Cebidae includes squirrel and Capuchin monkey, night and titi monkeys, Howler and spider monkeys, Uakaris and sakis. They are inhabited in most tropical regions of the earth.
