Tentacle

 

a movable outgrowth on the bodies of coelenterates, mollusks, annelids, bryozoans, brachiopods, pogonophores, pterobranchs, and other invertebrates. Tentacles are usually located at the front end of the body and serve to capture food; sometimes they are involved in respiration and palpation. In coelenterates the tentacles abound in stinging cells. In gastropods they are used for palpation and olfaction, while in cephalopods they are used for capturing prey and for locomotion.
