Until the 20th Century there were nine tiger subspecies that probably numbered over 100,000 animals. They included the giant 660-pound, or 300 kilo, Siberian (Pantera tigris altaica) and Caspian (Pantera tigris virgata; now extinct) tigers as well as the relatively small—and now also extinct—200-pound (90 kilo) Balinese tiger. Depending on whether there are any remaining South China tigers—nobody has seen one in years—there are either 5 or 6 tiger subspecies remaining in existence; all are endangered. All tiger subspecies put together currently amount to fewer than 3,000 endangered tigers remaining in the wild.
