What is the real cause of the death of the lost finless porpoise in Hangzhou?

? 1 1 9/month/around 5: 40, some citizens in Yuhang Street broke the news that a creature suspected of finless porpoise was found swimming in the water near Nantiaoxi, with a total length of 1 meter to 1.5 meters, and jumped out of the water from time to time. Fishermen nearby said that this finless porpoise should have appeared for two or three days. At first, it was thought to be an oversized snail, because someone had caught a snail weighing more than 100 kg before. Most finless porpoises live in the Yangtze River basin. Some people call them smiling angels because they have water sprite, round heads and smiling mouths. The finless porpoise belongs to mammals, cetaceans, dolphin family and finless porpoise. Has existed on the earth for 250 million years.

? The relevant departments have known the information for four days, because it has been in fresh water for too long, which has a great impact on its health. Because finless porpoises breathe with their lungs, they will surface for air from time to time. Fishery officials said that this finless porpoise belongs to the East Asian finless porpoise, a national second-class aquatic wild animal. Generally live in Qiantang River or Taihu Lake basin, where sea water and light meet. Of course, its main habitat is mainly seawater, and the lost place is freshwater. It must have strayed into its lost waters through some tributaries, and it is a gregarious animal, living in groups and leaving.

At that time, the staff of Ocean Park came to arrest. At that time, two divers were divided into two ways, one was pulling the net and the other was arresting. It took several hours to catch it for fear of scaring it. Then the diver put it on a stretcher covered with velvet and poured water for it. Originally, I was going to send it to Ocean Park for a physical examination before releasing it. Unfortunately, because the finless porpoise was timid by nature, on the way back, it had a stress reaction and died. Of course, the final cause of death will not be known until the final autopsy.
