Friday Eco-Fact: Australia’s Lesbian Koalas?

I was searching around the web today and stumbled upon this weird piece of information concerning Australian koalas:

Female koalas indulge in lesbian “sex sessions”, rejecting male suitors and attempting to mate with each other, sometimes up to five at a time, according to researchers.

The furry, eucalyptus-eating creatures appear to develop this tendency for same-sex liaisons when they are in captivity. In the wild, they remain heterosexual.

Scientists monitoring the marsupials with digital cameras counted three homosexual interactions for every heterosexual one.

“Some females rejected the advances of males that were in their enclosures, only to become willing participants in homosexual encounters immediately after,” say the researchers.

“On several occasions more than one pair of females shared the same pole, and multiple females mounted each other simultaneously. At least one multiple encounter involved five female koalas.

“One theory put forward by the researchers is that the females do it to attract males; another is that it is simply hormonal, or that it is a stress reliever. [NZ Herald]

Obviously these scientists from the University of Queensland have nothing better to do with their time.
