Born to be BIG!
A newborn gray whale is around 15 feet long at birth and weighs around 1,500 pounds. Calves may gain 60 to 70 pounds each day on their mother's fat-rich milk. They reach 18 to 19 feet in length in their first three months of life. By the time they're adults, gray whales weigh from 30-40 tons (27,200-36,300 kg).
