In general, a 'proboscis' (from
Greek ''pro'' "before" and ''boskein'' "to feed") is an elongated appendage from the head of an
animal. The most common usage is to refer to the tubular
feeding and
sucking organ of certain
invertebrates like
insects,
worms (including
proboscis worms) and
mollusks. The
elephant's trunk is also called a proboscis. An abnormal forehead appendage that sometimes accompanies
cyclopia is also called a proboscis. The term is used for
primate organs as well: an elongated human
nose is sometimes facetiously called a proboscis and the
Proboscis Monkey is named for its enormous nose.
The correct Greek plural is ''proboscides'', but in English it is more common to simply add ''-es'', forming ''proboscises''.
Notable mammals with some form of proboscis are:

elephant family (see
