porpoises

Porpoises are small marine mammals closely related to dolphins, characterized by their rounded faces and spade-shaped teeth. They inhabit coastal and some deep-sea waters worldwide, navigating using echolocation—sending out sound waves to locate prey and avoid obstacles. Porpoises are generally shy and less social than dolphins, often seen alone or in small groups. They are intelligent, agile swimmers that feed mainly on fish and small squids. As mammals, they breathe air through a blowhole and give birth to live young, caring for their babies and sharing a vital role in ocean ecosystems.
