prehensile hand
Quick Summary
A prehensile hand is adapted for seizing or grasping, often by wrapping around an object. This grasping ability is a key characteristic found in many primates, enabling them to climb, leap, and run in trees.12
The primate hand typically has five digits, though some species have reduced thumbs. The opposable thumb is crucial for skilled manipulation, allowing for a precision grip that is particularly developed in humans. This opposability, where the thumb can face the fingertips, is fundamental for picking up small objects and performing delicate tasks. While many primates possess prehensile hands, the degree of manipulative dexterity varies among species.23

Vertical-clinging primates such as the tarsiers or small, squirrel-like quadrupeds such as the marmosets—all of which have prehensile feet but not completely prehensile hands—by remaining or becoming small, have avoided the evolutionary pressures that have impinged on larger primates.
