Group sex, prostitution, masturbation -- every sexy thing we humans do, says Carin Bondar, animals do too, and a whole lot more we, thank goodness, can't (see topic: chastity belts).

Bondar, a biologist, hosts the truly astonishing "Wild Sex" video series on earthtouch.tv, where over two seasons she's been using science and uberwatchable storytelling to tell surprising tales of animal mating.

As she says: "We hit topics hard, and not just for the quirk factor, but because there is a lot of cool science behind so many strange mating rituals."
