Courting pair of southern right whales underwater, Eubalaena australis. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating. The male is below, upside down and trying to access the female belly-to-belly. However, the female does not want to mate, so she has positioned herself upside down at the surface so that the males in the courting group cannot reach her genital slit.
