One of the last Yangtze River

One of only four species of river dolphin is officially extinct; the last member of the species probably died sometime in the last few months. Just thirteen were found in the last survey a few years ago, and the 2006 survey found none. The last member in captivity died in 2002.

Douglas Adams wrote movingly about the Yangtze River dolphin in Last Chance to See, excerpts of which are posted at flying squid blog. The dolphins — which are extinct as a result of human activity, including the Three Gorges Dam — had a hard life over the last decades. They navigated by echolocation, and all the human activity in the Yangtze created constant white noise. It’s unspeakably sad to imagine the experiences of the last Yangtze River dolphins.
The Yangtze River dolphin is the first large mammalian species to go extinct in fifty years, and the first cetacean species to die from human causes in modern history. The other three river dolphin species are also endangered.
Incredibly fucked up.
