Illustration for article titled Kangaroos and koalas have three vaginas

Here's a little fun fact for your next Australia-themed dinner party: female marsupials all have three vaginas. That includes kangaroos, koalas, quokkas, and those cube-pooping wombats.


From Ed Yong at National Geographic:

This set-up is shared by all marsupials – the group of mammals that raise their young in pouches. Koalas, wombats and Tasmanian devils all share the three-vagina structure. The side ones carry sperm to the two uteruses (and males marsupials often have two-pronged penises), while the middle vagina sends the joey down to the outside world.
