These monkeys are gonna make you an offer you can’t refuse.
Primate researchers in Indonesia say a monkey mafia rules over an Indonesian temple. The mischievous macaques — that deceptively sweet faces take tourists’ belongings, only to send them back in exchange for food, according to New Scientist. They have exchanged about everything from hats to wads of cash.
Locals have long observed the monkeys’ rude behavior at the Uluwatu Temple in Bali. Videos of the famous temple show the animals to jump on unsuspecting tourists, stealing their stuff and hobbling back to their perches as they wait for a ransom.
But there is an important science on the basis of these aggressive animals, say researchers from the University of Liège in Belgium. Since the Uluwatu Temple is really the only place where the monkeys act this way, the behavior must be learned.
With each generation, the apes have grown bolder and have learned from their parents, if they stick to the stolen goods, she gets a yummy treat.
The monkeys are actually pretty smart to be able to this stunt by the generations, the scientists say.
