Narwhal females give birth every three years throughout their reproductive life, which starts at 4 to 7 years old. At birth, calves measure around five feet long, and by adulthood they can reach up to 16 feet. Narwhals weigh around 180 pounds as newborns, but can grow to weigh up to 1.8 tons. Females tend to be smaller than males, and males reach sexual maturity later, usually between 8 and 9 years old.
