Explanation:

[STC0010539]. There are only about a thousand Yangtze finless porpoises left in the wild, making them a severely endangered species. The Yangtze River, which is the longest river in Asia, serves as their natural habitat. The Yangtze finless porpoise, according to its name, does not possess a dorsal fin, which sets it out visually from other species in its genus that are otherwise very similar. They originally shared their native river with another species of dolphin known as the Baiji, which lived in the Yangtze river, but regrettably, that species became extinct in 2007.
