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 be somewhat lighter than normal even as adults.

Courting group of southern right whales, aerial photo. Mating may occur as a result of this courting and social behavior. The white whale seen here is a serious player named El Copulador (the copulator) and is often seen in mating and courting groups of southern right whales at Peninsula Valdes. His light coloration is an indication that he was a white calf, but he did not darken as he aged in the way most white southern right whale calves do.
