From IFL:
The manipulation of tools is something widespread across the animal world. While most use them to aid in feeding behaviors, some can even craft their own tools to solve complex problems. New research on elephants has shown one individual to be particularly adept at tool use, even mastering it to have a shower.
The individual in question is Mary, an Asian elephant living at Berlin Zoo, who was spotted one day by researcher and senior author Lena Kaufmann manipulating a hose and showering her body. In fact, Mary was so competent with the hose that she could coordinate it with her limbs, systematically showering her legs and even using the hose like a lasso and flinging it over her head to shower her back.
