The term 'Large Ocean Predator' can be summarized by the four-letter word 'ORCA'. Orcas, also known as killer whales, are the largest members of the dolphin family and are found in all oceans around the world. They are apex predators, meaning they have no natural predators, and feed on fish, squid, and marine mammals. Orcas are highly intelligent and social animals, living in pods of up to 40 individuals.
