Introduction to dugong:

Dugong Dugong's snout bends downward, and the front end becomes a snout, with short and dense bristles. The nostril is located at the back of the nose and has a valve. The tail leaf is horizontal, and there is a notch in the center of its rear edge. Paddle flippers have no nails. No nasal bones; The maxilla is obviously enlarged and bends sharply downward, and the mandibular joint is correspondingly extended and bends sharply downward. There are three premolars and three molars on both sides of the upper and lower jaws. Mainly distributed in the western Pacific Ocean and the Indian Ocean, they like the sea areas with good water quality and rich aquatic plants, and regularly float out of the sea for air exchange. Because female dugong occasionally has the habit of nursing her young in the water, dugong is often mistaken for a "mermaid". Since 4000 years ago, humans have been hunting dugong, eating meat to extract oil, making bones and making leather. So far, the number of dugong is extremely rare.
