What physical characteristics define the Family Cercopithecidae to which the vervet monkey belongs?

Answer

Downward-pointing nostrils and ischial callosities

The Family Cercopithecidae, representing Old World monkeys, is distinguished by several key anatomical features. These include nostrils that point downward, non-prehensile tails that cannot grasp objects, and the presence of ischial callosities, which are tough, padded areas located on the rumps of the monkeys. These traits differentiate them from New World monkeys and other primate groups.
