Many Primates Use Loads of Grooming Tools
Grooming is a common trait across animals of all types. But primates are among a few animals that use tools to aid their grooming routine. Mandrills may look menacing, but the apes actually spend a good amount of time fussing over hygiene. They fashion a tool out of grass and sticks to clean out their ears and prevent ear infections. Some mandrills use whittle twigs to clean under their nails. Macaques in Thailand have been known to swipe hair straight from people’s heads to use as floss. Chimps use small sticks to groom their skin, and bonobos sometimes use “sponges” made of chewed leaves and moss.
