Mandrill monkey makes ‘pedicuring’ tool (also just lookat’m, forchrissake)
“Mandrills are the fifth species of Old World monkey seen to modify tools”
"Animals have more time in captivity to carry out tasks that are not focused on looking for food or mating," he said. "So in zoos, you can occasionally pick up behaviours that are a little bit strange.
"In the wild this ‘pedicuring’ would be considered trivial," he explained. "But cleaning their ears with the same modified tool probably gave the animals some relief from the pain in their ears.
"So we’re witnessing the same behaviour that’s used in quite important tasks being adapted for a less important task," Dr Pansini said.
Um, sound familiar? This is the sort of thing I remind myself when I get bike/road rage, that my fight-or-flight response is neurochemically/physiologically gratuitous to the situation. I feel like every photo of a mandrill should just be captioned with WHAT!!! because, you know, they look like this.
