Hippopotamus
The hippo is a large, mostly herbivorous, semiaquatic mammal and ungulate native to sub-Saharan Africa. Adults average 1,500 kg for males and 1,300 kg for females. Despite its stocky shape and short legs, it is capable of running 30 kmh over short distances. The closest living relatives of hippos are cetaceans, from which they diverged about 55 million years ago.
