"Anthropophagi are not native to the Americas. They are to Northern and Western Africa and the Caroli Islands, but not here... They are not natural scavengers... Anthropophagi prefer fresh flesh, but there are things that drive them even more powerful than hunger... The female can breed, but she cannot bear. She lacks a womb, you see, for that location of her anatomy is given to another, more vital organ; her brain." The female places the child, wrapped in a protective sac, inside the male's mouth. The male has 2 weeks to find a host for it, or else it bursts the sac, and the father either chokes on it or the cub suffocates. Once placed inside a human victim, the cub develops and consume the host.
