Actually it was not declared extinct... The Black Rhino is critically endangered.

The Baiji Dolphin

Functionally extinct by 2006.

IUCN: database entry.

Scientific name:

Lipotes vexillifer.

Picture source (Wikipedia).

An expedition organized by The Baiji Foundation in late 2006 sought evidence that Baiji white dolphins still existed in their only habitat, the Yangtze river in China. Scientists from six nations on two research vessels travelled for almost 3500 kilometres to the Yangtze Delta, and then retraced their route. They were equipped with sophisticated optical instruments and underwater microphones, but were unable to detect any surviving dolphins. The Foundation published a report on the expedition and declared the species functionally extinct. What does functionally extinct mean? It means too few potential breeding pairs remain to ensure that the species will survive.
