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.

Rostrum and callosities of southern right whale, Eubalaena australis. Whale lice can be seen attached to the collosities, which are patches of thickened keratinized tissue, like calluses (thus the name). The pattern of callosities on a right whale are unique and serve as a way to identify individuals throughout their lifetime.
