The word abomination seems to have come up several times recently on this site. First, in several comments from a fellow disinfonaught, then again in this article. So I find it particularly ironic/amusing that I would then stumble upon this most glorious discovery, courtesy of The Huffington Post:
Scientists say they’ve discovered four species of Brazilian cave insects with sex-reversed genitalia. The females possess a penis-like organ, the males a vagina-like organ. This is the first documented example of animals with sex-reversed genitalia.
Sex-role reversal has been observed previously in animals — such as in African antelopes. But the “female penis” seen in the four species, all of which are in the genus Neotrogla, is a “completely novel structure,” Kazunori Yoshizawa, an associate professor at Hokkaido University and one of the scientists behind the new finding, told The Verge.
How do these insects have sex? During copulation, the female Neotrogla inserts a “highly elaborate” penis-like organ, dubbed the “gynosome,” into the male’s vagina-like opening.
