Sauce for the goose, sauce for the gander, cunnilingus for fruit bats

Ed Yong reports (with relish) on a successor to the Ig Nobel Prize winning study on fruit bat fellatio:

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.
