Gorillas are vegetarians that eat fruits, leaves, and roots. They are threatened by leopards and crocodiles in the wild. Male gorillas can grow up to 1.7 meters tall and weigh 135-220 kg, while females reach 1.5 meters and 70-90 kg. Gorilla families are led by a silverback male, who protects the family and leads them to new areas daily to find food. Gorillas live in rainforests where their habitat is threatened by deforestation and hunting, and their numbers have declined to under 700 in the wild with lifespans of around 35 years.
