Newborn harbor seal pup watches a Western seagull approach. The gull is trying to pick at placenta on the sandy beach as the seal pup, born just moments before, watches and tries to understand what is going on. Within an hour of being born, this pup had learned to nurse and had entered the ocean for its first swim.

Humpback whale lunge feeding on Antarctic krill, with mouth open and baleen visible. The humbpack's throat grooves are seen as its pleated throat becomes fully distended as the whale fills its mouth with krill and water. The water will be pushed out, while the baleen strains and retains the small krill.

Humpback Whale Fluke ID. Perfect view of the ventral surface of a humpback whale's fluke, as the whale raises its fluke just before diving underwater. The white patches, spots, scratches and scalloping along the trailing edge of the fluke make this whale identifiable when it is observed from year to year.

Mating pair of southern right whales underwater (on left). The gray adult whale on the right was formerly a white calf and, while it is not longer white, will remain lighter than normal throughout its life, Eubalaena australis, Argentina.

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.
