What is the gestation period for beluga whales?

Female belugas typically give birth to one calf every three years. Gestation lasts 12 to 14.5 months. Newborns are about 1.5 metres (4.9 ft) long, weigh about 80 kilograms (180 lb), and are grey in color. The calves remain dependent on their mothers for at least two years.
