Dugongs are large marine mammals that belong to the order Sirenia, which also includes manatees. They are herbivorous and primarily feed on seagrass found in shallow coastal waters. Dugongs have a streamlined body, flippers, and a distinctive tail that helps them navigate through their aquatic environment. These gentle creatures can grow up to 10 feet long and weigh between 400 to 1,100 pounds. Dugongs are found in warm coastal waters of the Indian Ocean, Pacific Ocean, and the Red Sea. They are considered vulnerable due to habitat loss, hunting, and environmental changes affecting their seagrass habitats.
