Western gorillas are smaller than the Eastern gorilla but not by much. They are very much the same in their physical appearance.
The gorilla is the largest of all primates, and there is no mistaking them for any of the others such as chimpanzees and monkeys.
Gorilla males are ready to mate when they are approximately 13 years of age. For females it is about 10 years of age. Gorilla mating happens all year round.
These explorers found a wild silverback gorilla in Rwanda. Are they in danger?
