Seeing in the Dark: How porpoises hear in one of the world’s busiest rivers

(October 21, 2013) Scientists are using medical technology to study the endangered Yangtze finless porpoise and their critical sense of hearing, used for navigation, to understand how these mammals are managing in the very busy and loud waters of China’s high-traffic Yangtze River. “In a noisy environment, they’d have a hard time hearing their prey or their friend. It makes it more difficult for them to conduct basic biological activities such as foraging, communicating, and navigating in the river,” said biologist and lead author of the survey, Aran Mooney.

China surveys Yangtze dolphin as extinction looms

(November 30, 2012) Chinese scientists have begun an expedition to count how many endangered finless porpoise remain in the Yangtze River. A similar survey in 2006 found only 1,800 of the animals, considered a national treasure, as well as a symbol of the mighty river itself and a reflection of the great waterway’s health.
