Size. Orcas are known for their long dorsal fin (the fin on the animal's back) and black-and-white coloring. Just behind the dorsal fin is a patch of gray called a saddle â because it looks like a riding saddle. An orca's body is cylindrical and tapers at both ends to form an aerodynamic shape. 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.
