There have been a viral video online. The video shows a Hygiene-Conscious Gorilla Walking Around on 2 Legs Just to Keep Hands Clean
The gorilla with name Louis was walking about his zoo enclosure upright like a human.
The 500-pound, six-foot tall gorilla is said to do this to keep his hands clean. And even crossing a tight-rope over a mud puddle in his enclosure to avoid getting dirty.
Footage of Louis’ walking shows the gorilla at Philadelphia Zoo upright on two legs. Rather than the typical knuckle-to ground stance.
The 18-year old male uses the upright stance to keep his food clean when his hands are full with tomatoes or other snacks, according to the Associated Press.
