Baby Beluga Whale

Reproduction
Female belugas typically give birth to one calf every three years. Most mating occurs between February and May, but some mating occurs at other times of year. It is questionable whether the beluga has delayed implantation. Gestation last 12 to 14.5 months.
Calves are born over a protracted period that varies by location. In the Canadian Arctic, calves are born between March and September, while in Hudson Bay the peak calving period is in late June and in Cumberland Sound most calves are born from late July to early August.
