Just because tigers, monkeys, and birds don't roll out of bed, jump in the shower, and turn on the tap, doesn't mean they don't have serious and involved ways to get clean. Bathing has been a central ritual of human civilizations for nearly all of recorded history but many animals, too, need to bathe to maintain hygiene and body temperature.

Several species of birds and mammals exhibit the behavior but—while functionally very similar—animal bathing often takes a radically different form.

In Japan, the Jigokudani Hot Spring in Nagano Prefecture is a popular bathing spot for Japanese Macaques. Macaques pay particular attention to grooming, and have been photographed lined up back-to-back in order to better groom each other. The macaque is also the only animal -- other than man -- known to wash its food.
