Apes represent the most advance primates. The western lowland gorilla is found in tropical rainforests in eastern Nigeria, Cameroon, southwestern Central African Republic, Equatorial Guinea, the Congo, Gabon, and Cabina. The eastern lowland gorilla is located in small pockets of tropical rainforest areas in the eastern part of the Congo. The gorilla lives in groups called troops and spends most of its time on the ground, although juveniles may by seen playing in trees. Each troop, from 7-20 gorillas, is led by a silverback male who protects and keeps the group together.
Gorillas are typically quiet and gentle.
Males will beat their chests as part of a ritual that sometimes includes hooting and thumping on the ground. This behavior is not clearly understood but seems to reflect excitement. Grooming is done to reinforce dominance and submission within the gorilla troop. Fun Facts 1. The intimidating chest-beating charge of a male gorilla is usually a bluff to scare off intruders while the rest of his band disappears into the forest.
