What can elephants do with there trunk?

Answer 1

The elephant can use it's trunk as a large straw to retrieve food and water to later put in its mouth.

the trunk can also be used as storage.

I think they use it for self defence if they are attacked as well along with thier powerful hind legs and sharp teeth.

Answer 2

they can use it for a lot of things to put water on them for a bath, and to pick food up and put it into their mouths.
