Black-and-white whales are also known as orcas, which is a five letter word. Orcas are the largest species of the dolphin family and are found in all oceans around the world. They are easily recognizable by their distinctive black and white markings. Orcas are highly intelligent and social animals, living in large pods and communicating with each other through a variety of vocalizations. They are apex predators, meaning they are at the top of the food chain and have no natural predators.
