The dugong is a large marine mammal that belongs to the order Sirenia, which also includes manatees. Dugongs are herbivorous and primarily feed on seagrass, making them important for maintaining healthy underwater ecosystems. They are often found in warm coastal waters of the Indian and western Pacific Oceans. Dugongs have a streamlined body, paddle-like flippers, and a distinctive tail that helps them swim gracefully. They can grow up to 3 meters (10 feet) in length and weigh around 400 kilograms (880 pounds). Unfortunately, dugongs are classified as vulnerable due to habitat loss and hunting, making conservation efforts essential for their survival.
