The Orca (Orcinus orca) is a black and white carnivorous marine mammal. Commonly known as the killer whale and also known as orca whale. The orca is the largest species of dolphin, being part of the family Delphinidae. (Delphinidae is within the Odontoceti or toothed whales, which is within the Cetacea or whales, so orcas are whales in the sense that all dolphins are whales.)
Usually growing around 5-8 meters long, orcas are known to be apex predators of the sea, as they have no natural predators.
