While you may not have already heard of a quoll, if you know enough about their mating rituals, you won't soon forget the species. Every winter, the females all go into heat at the same time, causing a breeding frenzy within the species. The males will try to mate with as many females as possible, grabbing their newest mate by the neck and dragging them off to do the nasty. Average mating sessions last up to three hours, but can go on as long as a full day. That's because the males don't release very many sperm at a time, so they must ejaculate multiple times to ensure their genes are passed on. Like many human males trying to compensate for something, the quoll males are violent and ruthless. In fact, throughout all the biting, scratching and screeching, many females end up killed in the process, only to be eaten by their angry partner.

As if nature wished to compensate the females for their suffering, many of the males put out so much energy during the mating season that they lose weight, start balding and die within only a few weeks of their sexual rampage.
