The name Orang-utan means "man of the forest" in Malay.

Like the other great apes, orangutans are remarkably intelligent.

Although orangutans are generally passive, aggression toward other orangutans is very common; they are solitary animals and can be fiercely territorial.

Orangutans are shy, solitary animals that are active during the day (they are diurnal). Exceptions are possible. (*)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.

Laughter might not be confined or unique to humans, despite Aristotle’s observation that "only the human animal laughs". The differences between orangutan and human laughter may be the result of adaptations that have evolved to enable human speech.

The animal that poses the biggest threat to the orangutan is man (who uses its habitat and sells young orangutans as pets).

Orangutans are an endangered species. They are decreasing in numbers quickly as they lose habitat to people.

In certain social human groups, UTAN also means "utente anonimo".
