The Cetacea are one of the most distinctive and highly specialized orders of mammals. They include whales, dolphins, belugas and porpoises. A group of cetaceans, known as a pod, usually consists of 10 to 50 animals, but on certain occasions, such as mass occurrence of food or mating season, may also include more than a thousand individuals in the groups. Also, interspecies socialization may occur.
