Observes the strange sex lives of animals, including fish that change sex in order to reproduce, and rodents that mate themselves to death.

Examines some unusual similarities between humans and several species of animals, like elephants, who mourn their dead and hold funerals for them, and chimpanzees, who recognise their own reflection.

Observes the strange tactics used by some animals to survive in the wilderness, such as giraffes that fight using their dense skulls, and the Tasmanian devil that makes good use of its deadly jaws.
