This just in – animals are gay too.

A group specializing in biological diversity is educating the public that same-sex attraction occurs in animals just as it does in humans. In honor of pride month, the Center for Biological Diversity released a video titled “Some Salmon are gay. Some bison are bi. Don’t let anyone tell you it isn’t natural.”

The 45-second video shows various animal species including salmon, bison, manatees, gray wolves, polar bears, elephants and more. “Wildlife biologists have documented more than 1,500 species in same-sex relationships,” reads a line in the video.

Located in Tucson, Arizona, the Center for Biological Diversity is a non-profit advocacy group for endangered species. It’s mission, the group states, is to keep wildlife diverse.

“We believe that the welfare of human beings is deeply linked to nature – to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law and creative media, with focus on protecting lands, waters and climate that species need to survive. We want those who come after us to inherit a world where the wild is still alive,” reads the group’s mission statement on its website,
