As its habitats are being usurped by man, the orangutan's population is decreasing and it is in grave danger of extinction. The orangutan has a large head with a prominent mouth area. Orangutans have senses very similar to ours, including hearing, sight, smell, taste, and touch. Their feet have four long toes plus an opposable big toe.
Orangutans can grasp things with both their hands and their feet.
Orangutans don't even have to leave their tree branches to drink, they drink water that has collected in the holes between tree branches. They also use leaves as cups to help them drink water. They live alone in large territories. The only long-lasting orangutan social group is the mother and offspring, who live together for about 7 years. When mating, the male and female orangutan stay together for only a few days.
