Beluga (Delphinapterus leucas)

As much as 40 percent of a beluga's body weight is blubber.


Belugas live in the Arctic and sub-Arctic waters of the world. The southernmost beluga population inhabits the St. Lawrence River estuary of Canada.


Belugas are a brownish-grey colour when they are born and turn slate grey within a few weeks. As belugas age, their skin loses pigment cells which causes it to turn white. Only the rims of their pectoral flippers and tail flukes retain their original grey shade.
