Did you know that Beluga Whales are not always white? As calves they are a darker gray color, which gradually lightens as they age. They will reach their full white color by around age 5. Females gestate for 14 months, and a newborn calf can measure 4-6ft (1.4m) long. Calves remain with their mothers for up to two years, and feed off of milk that is 28% fat in order to grow and maintain warmth in the cold waters.
Beluga Whales hunt using echolocation, a process that involves sending out clicks that then bounce off potential prey and echo back to the whale. The Beluga's large forehead contains a melon, which helps to amplify and focus these clicks. They feed on fish, worms and crustaceans, and consume 50-60lbs (22.6-27kg) a day.
