Kinkiness Beyond Kinky

Duck penises shoots out at 1.6 meters per second - this is all sorts of disturbing.

by Carl Zimmer of Discovery Magazine

There comes a time in every science writer’s career when one must write about glass duck vaginas and explosive duck penises.

That time is now.

To err on the side of caution, I am stuffing the rest of this post below the fold. My tale is rich with deep scientific significance, resplendent with surprising insights into how evolution works, far beyond the banalities of “survival of the fittest,” off in a realm of life where sexual selection and sexual conflict work like a pair sculptors drunk on absinthe, transforming biology into forms unimaginable. But this story is also accompanied with video. High-definition, slow-motion duck sex video. And I would imagine that the sight of spiral-shaped penises inflating in less than a third of second might be considered in some quarters to be not exactly safe for work. It’s certainly not appropriate for ducklings.

So, if you’re ready, join me below the fold.

This story is actually a sequel. Back in 2007, I wrote in the New York Times about the work of Patricia Brennan, a post-doctoral researcher at Yale, and her colleagues on the weirdness of duck genitals. The full story is here. (Brennan also appeared in a Nature documentary, starting at about minute 38:35.)

In brief, Brennan wanted to understand why some ducks have such extravagant penises. Why are they cork-screw shaped? Why do they get so ridiculously long–some cases as long as the duck’s entire body? As Brennan dissected duck penises, she began to wonder what the female sexual anatomy looked like. If you have a car like this, she said, what kind of garage do you park it in?
