Why A Little Mammal Has So Much Sex That It Disintegrates
National Geographic ^ | 10/8/13 | Ed Yong

Posted on 10/08/2013 10:32:52 PM PDT by Slings and Arrows

It’s August in Australia, and a small, mouse-like creature called an antechinus is busy killing himself through sex. He was a virgin until now, but for two to three weeks, this little lothario goes at it non-stop. He mates with as many females as he can, in violent, frenetic encounters that can each last up to 14 hours. He does little else.

A month ago, he irreversibly stopped making sperm, so he’s got all that he will ever have. This burst of speed-mating is his one chance to pass his genes on to the next generation, and he will die trying. He exhausts himself so thoroughly that his body starts to fall apart. His blood courses with testosterone and stress hormones. His fur falls off. He bleeds internally. His immune system fails to fight off incoming infections, and he becomes riddled with gangrene.

He’s a complete mess, but he’s still after sex. “By the end of the mating season, physically disintegrating males may run around frantically searching for last mating opportunities,” says Diana Fisher from the University of Queensland. “By that time, females are, not surprisingly, avoiding them.”

Soon, it’s all over. A few weeks shy of his first birthday, he is dead, along with every other male antechinus in the area.

Depends on whether it’s the ‘graybeards’ or ‘saddlebags’ you’re talking about...:)

I’ve always been fascinated by that painting, Ivan Albright’s “The Picture Of Dorian Gray”. He painted most of his works in a style called “ugly realism”. I guess his theme was to show that mortality is just plain gross.

Is it just me, or does Clinton look like he’s wearing orange jailhouse duds?

I’m sorry he’s gone.

Would have been interesting to see his version of Obeyme on a unicorn.

In 1996 President Clinton saw a photo of Juanita and reportedly said, "If I were a single man, I might ask that mummy out. That's a good-looking mummy!" According to the Associated Press, Peruvian scientists at the time called his remark "tasteless."

Albright referred to his style as "magic realism."

He spared no one, including himself. This is "Self Portrait."

They’re easy to open and you can put anything in them.

When I was a teenage boy, that's how I would've wanted to go.

As a former teen age boy I concur, and still at this age I really don't see a down side.
