Dugongs are large marine mammals that belong to the order Sirenia, which also includes manatees. They are herbivores, primarily feeding on seagrass found in warm coastal waters. Dugongs have a streamlined body, flippers, and a distinctive tail that helps them navigate through their underwater habitat. These gentle creatures can grow up to 10 feet long and weigh around 1,000 pounds. Dugongs are often referred to as "sea cows" due to their grazing habits. They are found in the Indian and western Pacific Oceans, and their populations are threatened by habitat loss and hunting.
