#JunkOff Is Turning Twitter Into a Wondrous and Definitely NSFW Sex Museum

By Diane Kelly on at

People following biologists on Twitter got a bit of a surprise this morning: their feed is full of genitals. They can blame Anne Hilborn (@AnneWHilborn) and a few of her colleagues at the Department of Fish and Wildlife Conservation at Virginia Tech.

Last night, Hilborn’s labmate Chris Rowe (@chrisrowebot) and their research supervisor Marcella Kelly (@marcellakelly) were posting pictures of animal genitals on their lab’s Twitter account (@Whapavt). When Hilborn added some more from her collection, one of their readers called it a “junk-off”. And thus a hashtag was born.

Says Hilborn, “I figured if I had lots of junk pictures, other biologists would too since pretty much all biologists love junk.” She posted the challenge, and got things started with a few snaps from her African field sites.

And before long, biologists were coming out of the woodwork to show off exactly how complex and bizarre animal genitals can get.

Botanists showed up to show that plants and fungi have their own version of genital organs: displaying heavily swollen anthers...

I have to say, though, that this fireweed's junk is engorged enough to make some mammals jealous... #JunkOffpic.twitter.com/w34o5Uw8JB
