In time for Halloween, Treehugger guides us :. New research published in the online journal PLoS ONE demonstrates for the first time that a non-human adult animal species regularly engages in oral sex behavior. While the behavior has been seen in juvenile animals before, this is the first time it has been observed in adult animals.
Outside of humans and a few other primates, oral sex is a rare phenomenon. But researchers have found male fruit bats do enjoy a little oral stimulation, and that the reasons females offer it go beyond simple pleasure. Min Tan of China's Guangdong Entomological Institute recorded and carefully observed the mating habits of 60 fruit bats she captured in the wild.
You may already know that fruit bats are among the few species besides humans to engage in fellatio, but new observations confirm they practice cunnilingus, as well. And yes — there's video evidence. Back inresearchers observed extensive evidence of fellatio among short-nosed fruit batsand concluded that in 70 percent of sexual encounters, the female bat would lick the shaft of her partner's penis.
Oral sexsometimes referred to as oral intercourseis sexual activity involving the stimulation of the genitalia of a person by another person using the mouth including the lips, tongue, or teeth and the throat. Cunnilingus is oral sex performed on the vulva or vaginawhile fellatio is oral sex performed on the penis. Oral sex may be performed as foreplay to incite sexual arousal before other sexual activities such as vaginal or anal intercourse  or as an erotic and physically intimate act in its own right.
Oral sex is widely used in human foreplay, but rarely documented in other animals. Fellatio has been recorded in bonobos Pan paniscusbut even then functions largely as play behaviour among juvenile males. The short-nosed fruit bat Cynopterus sphinx exhibits resource defence polygyny and one sexually active male often roosts with groups of females in tents made from leaves.
Earlier today, we brought you news of a sea lion that dances along to Backstreet Boys. This evening brings more news of animals partaking in an activity once thought to be the sole dominion of enlightened animals like us humans: Oral sex. Analysis of a colony of flying foxes in India found that males of the species perform oral sex on females.
All rights reserved. Oral sex in fruit bats is clearly a hot area of research. In just four years, the number of papers on this topic has doubled from, er, one to two.
In fact, we know of only animal apart from humans to regularly engage in fellatio — the short-nosed fruit bat Cynopterus sphinx. Tan captured 60 wild bats from a nearby park, housed them in pairs of the opposite sex and voyeuristically filmed their liaisons using a night-time camera. Twenty of the bats got busy, and their exploits were all caught on video. Male bats create tents by biting leaves until they fall into shape.

Regular readers of this blog know that while I think studying animal cognition, behavior, and communication is sometimes fun and always interesting, the real importance - the why should I care about this - is because by understanding animals, we can attempt to learn more about ourselves. I've written about this before. Here are the relevant excerpts:. When human adults show complex, possibly culture-specific skills, they emerge from a set of psychological and thus neural mechanisms which have two properties:.
