The genitals of the mallard (Anas platyrhynchos), female vagina on the left, male phallus on the right (size bar = 2 centimeters). An escalating sexual arms race between male and female mallards over which sex gets to control reproduction has resulted in increasingly longer phalluses and ever more elaborate vaginas.
