Outre un coquet maquillage naturel, les mandrills prennent soin de la propreté de leurs pieds en fabriquant des outils.
In the footage that Dr Pansini captured, a large male mandrill strips down a twig, apparently to make it narrower. The animal then uses the modified stick to scrape dirt from underneath its toenails.
“Mandrills have been seen to clean their ears with modified tools in the wild,” he told BBC Nature. “This was thought to help prevent ear infections and therefore might be an important behaviour in terms of hygiene.”
