Orca whales, also known as killer whales, are among the most iconic and fascinating marine mammals. Orcas belong to the family Delphinidae, which includes dolphins and other toothed whales. Their scientific name is Orcinus orca. Orcas are easily recognized by their distinctive black and white coloration. They have a large, robust body, with a white underside and black on the back and sides. They also have a prominent dorsal fin. Adult orcas can reach lengths of up to 30 feet (9 meters) and weigh as much as 10 tons. Orcas communicate with each other using a variety of vocalizations, including clicks, whistles, and pulsed calls. These vocalizations play an essential role in social interactions and hunting. Orcas are found in oceans around the world, from the Arctic to the Antarctic. They are highly adaptable and can inhabit both coastal and open ocean environments.
