Orcas, also known as killer whales, are black-and-white predators found in oceans around the world. They are highly intelligent and social animals, living in pods of up to 40 individuals. Orcas are apex predators, meaning they have no natural predators of their own, and feed on a variety of prey including fish, seals, and even other whales. They are an iconic species, and have been featured in many films and documentaries.
