Chinese Fruit Bats Engage in Some Kinky Behavior

A scientific paper published today on http://www.plosone.org details some interesting bat behavior. The article title really says it all Fellatio by Fruit Bats Prolongs Copulation Time. The paper's abstract goes on to state "A positive relationship exists between the length of time that the female licked the male's penis during copulation and the duration of copulation. Furthermore, mating pairs spent significantly more time in copulation if the female licked her mate's penis than if fellatio was absent."
