The Sulawesi Crested Macaque, also known as the Black Crested Macaque (and formerly the Celebes Crested Macaque), is native to the Indonesian islands of Sulawesi and Pulau Bacan.
Despite their lack of tails (only a stub tail), macaques are monkeys rather than apes.
Three hands! They are adept with hands and feet.
"Hold on a minute." (Does the face remind you of Michael Douglas?)
Clenched teeth mean friendship but yawning is a threat.
The crest/quiff -- raised when excited.
They live in small groups in rain forest but are mainly terrestrial rather than arboreal.
Their survival is threatened by habitat loss and the growing "bush meat" trade.
