A group of porpoises can be called a pod, school, herd or turmoil. Porpoises are social animals and typically live in small groups of 10 or fewer members.
Porpoises are marine mammals of the cetacean species that also includes whales and dolphins. They are usually smaller than dolphins, measuring between 5 and 8 feet in length. They can be distinguished from dolphins by their rounded heads, which have very short beaks compared to those of dolphins. Porpoises also have fused necks, meaning they cannot turn their heads without turning their bodies. Like dolphins, they are highly intelligent and can be taught a wide variety of tricks when living in captivity.
