The species likely to vanish forever within three decades include wellpublicised cases, such as the black rhinoceros and the Siberian tiger, and less well-known animals such as the Philippine eagle and the Asian Amur leopard.
Contrary to its name, the black rhinoceros is actually grey in color.
In the past few decades, several animal species have been labeled extinct, including the Chinese paddlefish, Yangtze River dolphin, Pyrenean ibex and western black rhinoceros.
