Fruit bats and their tongues
Tan M, et al. (2009) Fellatio by Fruit Bats Prolongs Copulation Time. PLoS ONE 4(10): e7595
I know it’s two weeks old, but it’s still amusing. To quote the article, “Our observations are the first to show regular fellatio in adult animals other than humans.”
What I find really funny though is how unrealistically precise they were with their timing. Duration of copulation measured to one hundredth of a second? Really? With precision of give or take half a minute?
“The average duration of penis licking was 19.14±3.45 s, representing about 8.7% of the average duration of copulation (220.29±26.19 s (N = 14)). [...] The pairs spent more time copulating if the female licked her mate’s penis [...] than on occasions when females did not show licking behavior (121.83±20.56 s, N = 6)”
Well, I guess that’s PLoS ONE for you.
