Mary, a 54-year-old Asian elephant at the Berlin Zoo, is the “queen of showering,” but her companion Anchali seems to have figured out how to exploit that habit to play pranks

Not only does Mary the Asian elephant prefer to shower herself, but she's really good at it. So good, in fact, that her dexterous bath-time ritual is the subject of a new study about animal tool use.

Researchers at the Berlin Zoo have documented sophisticated tool use by an Asian elephant named Mary, who demonstrated remarkable skill in handling water hoses for showering. The study revealed that Mary exhibited complex behaviors typically associated with advanced tool use.
