Iguanas, Koalas and Komodo dragons all have two penises.

February 3, 2010

True - this is known as a hemipenes (plural for the pair, singular: hemipenis), and is a trait of of male squamates (scaled reptiles e.g. snakes, lizards), and some species have hemipenes that are forked at each tip. The hemipenes are typically held inverted in the abdomen of the squamata, and due to this inversion hemipenes do not contain a fully sealed sperm channel like in a mammal, but rather an open groove that seals itself when the hemipenis is erect.

Update: in our haste, we managed to miss that the original claim sandwiched a marsupial in between two squamates. This is also true, koalas (along with opossums, Tasmanian devils, wombats, wallabies, and others) have what is called a bifurcated penis this differs from the squamata’s hemipenis as bifurcated penis is not inverted; female marsupials also have two vaginas and two uteri.
