Research led by UGA professor reports first routine tool use by wild capuchin monkeys
... significant things about this research is that we see
the behavior in an entire population and not in isolated individuals," said Fragaszy, who is considered one of the world's top experts on capuchin monkeys. "Also, it is the first time this behavior has been observed in wild capuchins." Another study,...

Violent ocean motion no magic potion for reefs
