Other forms: hippos
A hippo is the huge river animal of Africa with an enormous mouth. A yawning hippo, a pod of hippos, hippos in the shallows.
It is short for hippopotamus and is what almost everybody says. The wide gape is a threat display rather than a yawn, and it works: a hippo kills more people in Africa each year than lions and crocodiles together.
