When a female clownfish dies, a male clownfish can switch sexes and reproduce with other females. Some morpho butterflies have one male wing, and one female. In some populations of giraffes, about 95% of sexual activity is homosexual. In his book, “A Little Queer Natural History,” science writer Josh Davis gives a sampling of the enormous variety of gender and sexual behaviors in the plant, fungal and animal world and the ways some scientists have twisted themselves into knots to find non-sexual explanations for gay sex in animals. We talk to Davis about the gender fluid, intersex, asexual, gay, gender changeable, multi-sexual, rainbow splendor of the natural world.
