An elephant's trunk is essentially a modified nose comprising muscle and no bone. When the trunk is used for drinking, as in the photo above,
the elephant sucks water into the trunk and then squirts the contents into its mouth. In adults, the trunk when used like this can hold about 10 to 12 liters.
Elephants can't drink directly through their trunks as this would be like sucking water through the nose, which would cause them to drown.
Permitted Uses: See Terms of Use.
