Sawfish Reproduce with Virgin Births

Virgin birth isn’t just for biblical tales. Scientists at the Florida Fish and Wildlife Conservation Commission found that 3 percent of pregnant female sawfish had no recent contact with males. Reproduction without input from a male has been discovered before, in sharks, snakes, and fish, but not in vertebrates in the wild. The fish species has been driven close to extinction, and the female-only reproduction may help it survive.
