A Proboscis is an elongated appendage on the head of an animal.


Commonly found in invertebrates, such as insects, worms and gastropod molluscs, the proboscis is used as a long, slender, tubular feeding organ to suck fluids.


Vertebrates with some form of proboscis include elephants, tapirs, elephant shrews, aardvarks, numbats and proboscis monkeys.
