According to the report, on May 7 1 1, volunteers from non-governmental wildlife protection organizations came across a dead finless porpoise larva at Dongtan Beach in Nanhui, Shanghai. On the same day, the staff of the fishery administration station in Pudong New Area went after receiving the report. Because the pollution of the body was avoided, it was buried in situ.

The volunteer team issued a briefing saying that when accompanying foreigners to Shanghai to visit the site of an original bird-watching resort (commonly known as "wooden plank road area") in Nanhui Dongtan, Pudong, a beach about 1 10 cm long was found at the corner between the fourth phase of Nanhui Dongtan (reclaimed land) and Century Tang (levee). According to the staff nearby, this dead animal has been stranded here for about ten days.

On June 7th, 2007 1 1: 20, the law enforcement officers of the fishery squadron of the Law Enforcement Brigade of the Agriculture Committee of Pudong New Area were instructed to go to Guan Hai Park in Lingang. Under the guidance of Mr. Long Jiang, a member of Shanghai Wildlife Conservation Association, a young finless porpoise that has been highly decomposed was discovered.

According to the measurement, this young finless porpoise is about 1 14cm in length, 33cm in ventral height and 15kg in weight. The whole body is well preserved, the right fin falls off due to decay, the teeth are arranged neatly, and the nose is tilted. It is easy to judge that it is a young finless porpoise from its appearance.
