how big is a baby orca whale
A female killer whale will give birth every three to 10 years, to one offspring at a time. The gestation period usually lasts for around 17 months. A baby orca is called a calf, and they are about 8.5 feet (2.6 m) long and 265 to 353 lbs. (120 to 160 kg) at birth, according to Sea World. Calves nurse for 5 to 10 seconds at a time, several times an hour. This goes on day and night until the calf has mature enough.
