These Two Newly Discovered HORNY Marsupials Die After Having Sex

Two new species of marsupials, known for their intense and often fatal sexual behaviors, have been discovered by the scientists of Queensland University of Technology.

As Science Alert reports, the antechinus is a small mouse-like animal that is known for the male’s “suicidal sexual” tendencies.

These antechinuses have become famous for their strange sexual habits. Each year, all the males in the species go on a mating and fighting rampage, which only ends when they’re dead.

Lead researcher Andrew Baker explains that the breeding period is two to three weeks of “speed-mating,” complete with “testosterone-fueled” males seeking as many females as possible, for up to 14 hours at a time.

Baker says this results in a rise of stress hormones and causes the males’ immune systems to collapse. Thus, they all drop dead — sometimes even before the females give birth.

WOW! Seriously? Such fatal sexual activity indeed.

However, the Tasman Peninsula Dusky antechinus is already under threat of extinction as a result of habitat loss. 

Most of its limited habitat falls within state forest, which is being logged. This species now apparently only lives in tiny, fragmented stands of intact forest that are under threat. It’s a shame that mere moments after discovery, these little Tasmanian marsupials are threatened with extinction at human hands,” said Baker.

Although human impacts are putting added pressure on the species, their suicidal breeding habits make the species more vulnerable to environmental changes, as the survival of the species relies entirely on the females each year.

The team is now hoping to have the new species added to Australia’s federal threatened species list in order to help protect them. 

It’s exciting that we’re finding new species but at the same time might we lose some of these species almost before we’ve even discovered them or almost as soon as we’ve discovered them,” Baker adds.
