This tiny marsupial is a bit funny in its behavior. This weird animal should be nicknamed the “suicide mater” because the animal spends so much energy in a sort of marathon mating that could last for 14 hours. And this leaves the animal spent, exhausted, and dying.

Studies have indicated that these animals engage in this strange promiscuous mating behavior to ensure that their sperm and genes win against other males that also mate with the same females.
