How much water can an elephants trunk hold ?

Answer 1

Elephants suck water up into the trunk (up to fifteen quarts [14.2 liters] at a time) and then blow it into their mouth. Elephants also inhale water to spray on their body during bathing. On top of this watery coating, the animal will then spray dirt and mud, which act as a protective sunscreen.

Answer 2

Not a lot, maybe as much as 2 to 3 liters. Depends on the size of the elephant.
