Porpoises are friendly marine mammals that belong to the same family as dolphins. They are known for their playful nature and can often be seen swimming in groups. Porpoises have a rounded body, a flat snout, and a small dorsal fin. They are usually gray or dark blue in color, which helps them blend into the ocean waters. These creatures are found in coastal waters around the world and are known for their intelligence. Porpoises communicate using a series of clicks and whistles, similar to whales. They primarily feed on fish and squid, making them skilled hunters in their underwater environment.
