River Dolphin - Extinction of The Baiji

Extinction of The Baiji

On December 13, 2006, the baiji (Lipotes vexillifer) was declared "functionally extinct", after a 45-day search by leading experts in the field failed to find a single specimen. The last verified sighting was in September 2004. In August 2007, reports surfaced that a man saw and videotaped what appears to be a baiji in the Yangtze River. A team of scientists attempted to verify the sighting beginning in September 2007.

Overfishing, damming and subaquatic sonar pollution (which interfered with the dolphins' sonar-based method of locating food), is believed to have led to their extinction. Reuters news reported this as their first record of an aquatic mammalian extinction in 50 years.
