This video shows a large hippo crunching and eating whole watermelons. Watch the strong jaws of the hippo crush the watermelon in one bite. The hippo smashes the watermelon in one go and reallly seems to enjoy himself.
This video was filmed at the Nagasaki Biopark in Japan, where the hippo watermelon feeding happens twice a day. The keeper places the watermelon in the hippos mouth and then with a big crunch it smashes.
