A porpoise is a small marine mammal belonging to the family Phocoenidae. They are closely related to dolphins but are generally smaller and have a more rounded body shape. Porpoises are known for their intelligence and social behavior, often found in groups called pods. They primarily inhabit shallow coastal waters and are known to feed on fish and squid. Porpoises have a distinctive appearance, featuring a blunt snout and a smaller dorsal fin compared to dolphins. They communicate using a series of clicks and whistles, which helps them navigate and locate prey. Conservation efforts are important for protecting porpoise populations, as they face threats from habitat loss and fishing activities.
