The term 'Predatory Sea Creature' can be summarized by the four-letter word 'ORCA'. Orcas, also known as killer whales, are large marine mammals that live in oceans around the world. They are apex predators, meaning they have no natural predators, and feed on fish, squid, and other marine life. Orcas are highly intelligent and social animals, living in pods of up to 40 individuals. They are also known for their distinctive black and white markings.
