GORILLAS

 

Western gorillas (Gorilla gorilla) and eastern gorillas (Gorilla beringei) live in tropical Africa ranging from Nigeria, Cameroon, Angola, Gabon, Central African Republic, Congo, through the Democratic Republic of Congo, to Rwanda and Uganda. Like chimpanzees, they make nests to sleep in every night. Gorillas are mainly ground-dwelling, but especially lowland gorillas will forage for fruit in trees. Adult males are much larger than females and a group is usually about 10 individuals, consisting of one adult male and several adult females with their young, although this can vary.
