The trunk is the elephant's feeding organ, but it doesn´t actually eat with it; it uses the trunk to grab food and take it to its mouth. Same with water.
Sparrows use their beak to grab food. Houseflies have a proboscis, a sort of tube to suck liquified food. As for many fish, they have protractile mouths which allow them to suck their prey in a fraction of a second; some fish like the moray eel have two sets of jaws to grasp and swallow prey, and some, like lamprey, have disc-shaped mouths with many sharp teeth to suck the blood of other fish (although wether lamprey should be considered real fish is not very clear).
