After three days of searching, an injured finless porpoise was finally discovered Thursday afternoon in the Poyang Lake, China's largest freshwater lake.

Finless porpoise protection volunteers in Jiangxi Province discovered a large fishhook on the back of the endangered animal, using a long-focus lens on Feb. 5, but the the animal disappeared before they could help.

Jiangxi Provincial Fishery Department initiated a search for the animal after being informed by volunteers. Hydrobiology experts from the Chinese Academy of Sciences also joined the search.

Experts said the porpoise seemed to be in stable condition, and are making plans to capture the porpoise to offer it assistance.

Zhan Shupin, a department employee, said it was hard to catch it since it was in a water channel 400 meters wide and 20 meters deep.

Rarer than China's giant panda, the finless porpoise is a mammal similar to the dolphin, and now teeters on the brink of extinction, with a population of around 1,000. About 450 live in the Poyang Lake.
