A tentacle or bothrium (plural: bothria) is one of usually two or more elongated flexible organs present in animals, especially invertebrates. The term may also refer to the hairs of the leaves of some insectivorous plants. Usually, tentacles are used for feeding, feeling and grasping. Anatomically, they work like other muscular hydrostats. The word tentillum is a diminutive, but although it literally means "a little tentacle", it usually refers, irrespective of size, to a side branch of a larger tentacle. In some cases such tentilla are specialised for particular functions; for example, in the Cnidaria tentilla usually bear cnidocytes, whereas in the Ctenophora they usually bear collocytes.
