White southern right whale calf underwater, Eubalaena australis. About five per cent of southern right whales are born white due to a condition known as grey morphism and will gradually turn dark as they age. They are not albino (which is a complete lack of pigmentation). Sometimes referred to as "brindled", the white coloration is a recessive genetic trait and only lasts a few months. Typically, but not always, white calves will become much darker as they mature but will still somewhat lighter than normal even as adults.

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.
