While many people may not realize it, wombats poop in cubes and scientists have figured out how they accomplish this unusual feat.
According to a report from Gizmodo, the usually shaped scat serves the Australian marsupials in two ways — first, they use it to mark their territory and second to attract mates. Each piece of dung measures 2 centimeters across, and each time they go to the bathroom, they produce at least four to eight bits. Each night, one wombat can create 80 to 100 poop cubes, which they can stack. The shape of the waste is an evolutionary adaptation, and the form keeps it from rolling away.
Patricia Yang, a postdoctoral fellow in mechanical engineering at the Georgia Institute of Technology, investigated the unusual poop structure of wombats, which are the only animals known to create this unusually shaped dung.
