General: tentacles

A tentacle is one elongated flexible organ present in animals, especially invertebrates. Usually, tentacles are used for feeding, feeling and grasping.

Oftentimes, in art, plants have tentacles as well, in the form of movable vines. And, naturally, other animals and monsters are depicted with tentacles.
