In order to keep their fur clean, monkeys scratch themselves with their long toes ending in nails.
Mountain gorillas, on the other hand, as the name suggests inhabit high mountains. Gorillas like to live in groups of five to thirty individuals. Although gorillas may look friendly, they are not. They are a very family-oriented and peaceful species. The male can reach up to 1.9 meters in height and weigh up to 220 kilograms! Females, on the other hand, are much more petite and weigh about 98 kilograms and are about 1.5 meters tall.
These animals feed mainly on plants, stems and roots, but they also eat fruits and small insects. Because gorillas have a very massive body structure, they need to provide their body with large amounts of food. During the day, an adult gorilla can eat up to 25 kg of vegetation!
The female's pregnancy lasts 9 months and the young gorillas weigh just over 2 kilograms at birth. In captivity, gorillas live up to about 35 years.
