It's a wonder I didn't found this earlier, really. I've read about some facts here and there but I never figured there are documentaries on the topic. The film is very impressive. It contains studies on more that a dozen species from flies to lions. I knew a bit about homosexual behaviour in males, but I had no idea it is seen in females no less. Also I couldn't imagine it can be found in so many species. No wonder these studies have been repressed for a long time because there's no way you can call it an anomaly.

Some of my favourites are:

The romantic relationships of dolphins that may last a lifetime.



The affectionate female-female couples of Japanese macaque.



The three-way union of ducks.



The peculiar mating of octopuses. The top one, which is by the way a different species, well... tops. Brave fellow, ha?))
