What key physical feature is shared by all members of Family Atelidae, including woolly monkeys, spider monkeys, and howler monkeys?

Answer

The presence of a fully prehensile tail functioning as a fifth limb

The defining characteristic linking the woolly monkeys, spider monkeys, and howler monkeys within the specialized family Atelidae is the presence of a tail that is fully prehensile. This means the tail has the ability to grasp and hold objects securely, effectively operating as a fifth limb for the animal. This adaptation is critical for navigating the dense forest canopy, allowing these primates to maintain secure suspension while reaching for food resources. The text specifically notes that this feature is utilized by the woolly monkey for suspension while feeding, illustrating its vital role in their arboreal lifestyle, which is a common evolutionary pathway shared by this grouping of large American primates.
