Prehensility

Appendages that can become prehensile include:

Hands and feet	The hands of primates are all prehensile to varying degrees The front paws of raccoons and many of their relatives are prehensile. The feet of passerine birds can be prehensile
Tails	New World monkeys have prehensile tails Tails of many extant lizards (geckos, chameleons, and a species of skink) are prehensile Seahorses grip seaweed with their tails. Several fossil animals have been interpreted as having prehensile tails, including several Late Triassic drepanosaurs,[2] and possibly the Late Permian synapsid Suminia.[3]
Tongue	Giraffes' tongues in particular are prehensile Some other ungulates' tongues are also prehensile to a lesser extent	Giraffe's prehensile tongue
Nose	The noses of elephants and tapirs are prehensile
Lip or lips	Lips of lake sturgeon, orangutans, horses, and rhinos Upper lip of the West Indian manatee
Tentacles	Arms of octopuses, squid, and the cirri of nautiluses To a limited extent, the tentacles of sea anemones, hydra, and a few other invertebrates can grasp and move objects

Prehensility affords animals a great natural advantage in manipulating their environment for feeding, climbing, digging, and defense. It enables many animals, such as primates, to use tools to complete tasks that would otherwise be impossible without highly specialized anatomy. For example, chimpanzees have the ability to use sticks to obtain termites and grubs in a manner similar to human fishing. However, not all prehensile organs are applied to tool use; the giraffe tongue, for instance, is instead used in feeding and self-cleaning.
