Orca

Orcas, also known as killer whales, are the largest members of the dolphin family. They are easily recognizable by their striking black and white coloration and robust bodies. Adult males can reach lengths of up to 9 meters (30 feet) and weigh over 5,400 kilograms (12,000 pounds), while females are slightly smaller. Orcas are apex predators, known for their intelligence, complex social structures, and diverse hunting techniques. They live in matriarchal pods, which are family groups led by the oldest female. These pods can consist of up to 40 individuals and are known for their sophisticated vocalizations used for communication and echolocation. Orcas are found in all the world's oceans, from the frigid Arctic and Antarctic regions to tropical seas. They have a varied diet that includes fish, squid, and marine mammals such as seals and even other whales. Their adaptability and intelligence make them one of the most successful marine predators. Despite their name, orcas are not a threat to humans in the wild. They are a symbol of marine conservation efforts, as they are affected by pollution, habitat loss, and depletion of prey species.
