Explores non-human animal sexual behaviors that lie outside exclusive male-female partnerships, including intersex animals, animals that change between male and female, and same-sex relationships between animals. Drawing on research and interviews with experts and scientists, the author makes the point that nature contains within it a wide variety of sexual expressions among animals, including humans, and that being a queer human is part of the breadth and diversity of the natural world. Includes a glossary and further resources.
