List RulesAll animal species on this list have exhibited homosexual behavior, confirmed by scientists.

Animals with same-sex partners can be found all over the globe, across 1,500 species. But can animals be gay? Scientists say it’s complicated. While there are studies that show widespread animal homosexual behavior, the reasons may vary. Possibly, animals are showing dominance, practicing for mating, or simply blowing off steam.

Scientist Petter Bockman explains the lack of research about gay animals: "The theme has long been taboo. The problem is that researchers have not seen for themselves that the phenomenon exists or they have been confused when observing homosexual behavior or that they are fearful of being ridiculed by their colleagues. Many therefore overlook the abundance of material that is found. Many researchers have described homosexuality as something altogether different from sex. They must realize that animals can have sex with who they will, when they will and without consideration to a researcher's ethical principles."

The 2006 Against Nature? exhibit at the Natural History Museum at the University of Oslo in Norway documented homosexual and bisexual behavior across 1,500 species. The exhibit’s goal was to “help demystify homosexuality among people” and to “reject the all too well-known argument that homosexual behavior is a crime against nature.”
