The Chinese River dolphin (Lipotes vexillifer) or Baiji is a river dolphin. It was found only in the Yangtze River in China. The baiji was declared extinct in 2007 by the Chinese Academy of Science.[source?]

Description[change | change source]

The baiji is a graceful animal, with a long, narrow and slightly upturned beak and a flexible neck. As opposed to some other freshwater dolphins, like the Indus River dolphin, its eyes are functional, although greatly reduced. Its coloration is bluish-gray to gray above and white to ashy-white below. It weighs 135 - 230 kg (300 - 510 lb) and measures as much as 2.5 m (8.2') in length.
