Plot
From homosexual penguins and sex-transitioning fish to pregnant male seahorses and sexually dominant female bonobos, thousands of species defy our expectations of gender and sexuality. Director Drew Denny takes the nature documentary to a whole new level in this eye-opening and entertaining expedition to the places David Attenborough overlooks, where giant duck penises and corkscrew vaginas take center stage. Debunking myths that females are “inferior” and being queer is somehow “unnatural,” Second Nature explores the 1500+ animal species that engage in same-sex sexual behavior and parenting, change sex, form matriarchies, and more.
