Beluga Whale: 14 – 15 months (females give birth to a single calf every 3 years). Blue Whale: 11 – 12 months (females breed every 2 – 3 years). Killer whale: 15 – 18 months (average is about 17 months). Females give birth every 3 – 5 years. Note: Killer whales are part of the dolphin family and are the largest among the dolphin species.

Calves are most often born tail first. Though quite rare, the female may give birth to twins. The newborn’s energy needs are taxing and a female will struggle to provide for two.
