Gorilla
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. They are classified in the genus Gorilla which is divided into two species: the eastern gorillas and the western gorillas (both critically endangered), and either four or five subspecies. They are the largest living primates. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after the species of "Pan"; the chimpanzees and bonobos.

The most populous large mammal is the lechwe antelope, with more than 60,000. It is a bit larger than an impala with elongated hooves and a water-repellent substance on their legs that enables rapid movement through knee-deep water. They graze on aquatic plants, and like the waterbuck, take to water when threatened by predators. Only the males have horns.
