Neophocaena asiaeorientalis better known as the jiangtun or the Yangtze finless porpoise is a species of of toothed whale in the porpoise family Phocoenidae, is endemic to the Yangtze River in China. They are one of the world’s only freshwater porpoises and tend to be found in shallow bay areas, swamps, lakes, and estuaries where the feed upon various species of fish and crustaceans. Like most cetaceans they are a highly social species which lives in pods as little as 3 to as many as 20 individuals. Rather than vocalizing via chirps and whistles, as most dolphin species do, these porpoises use echolocation and ultrasonic pulses to communicate with one another. They are also know to sleep in shift like cycles, with active porpoises occasionally supporting there lethargic compatriots with there backs. Tho this is particularly common with parents and there offspring. Reaching some 5 to 7.5ft (1.5 to 2.3m) in length and 100 to 160lbs (45 to 72kg) in weight, with males being larger than females, the Yangtze finless porpoise is one of the smaller cetaceans. They sport large curved flippers with pointed tips, a stocky grey to black body that slims towards the tail, and a unique very steep head lacking a beak. Instead of a dorsal fin, these porpoises have a dorsal ridge or "groove" that is covered in varying rows of tubercles. Breeding occurs in late spring and early summer, and after a ten to 11 month pregnancy a mother Yangtze finless porpoise will give birth to a single offspring called a calf. Under ideal conditions a Yangtze finless porpoise may live upwards of 30 years. The Yangtze finless porpoise is considered critically endangered and it is estimated that only about 1,000 remain.
