I have been fascinated by elephants drinking. It sounds simple really: Aspirate water, fill the truck and blow it out into the mouth ! But how do THEY both blow and drink at the same time ? We humans cannot do that ! Water would go through our glottis and enter the lungs. I cannot find any information on that and the Smithsonian Zoo is not answering either.
I don't think the water is expulsed from the trunk by peristalsis either as the jet they can make is pretty high pressure
Some unavoidable spilling...
Don't step in my drink !
"Mom you got your drink, now I want mine !"
Now you know why baby elephants don't have tusk ! They would stab their mother !
When the right breast is empty, go around mom...
... and drink the left breast !
This female as a backward-growing tusk! Elephant birth defect !
Her left tusk seems less worn out, probably she did not find a useful way to use it !
