The final Bali tiger is thought to have been
seen back in 1937, the last-remaining Caspian tiger was found in the
1950s, and the Javan tiger went extinct sometime in the 1980s. The
six subspecies that have survived include: the Bengal tiger, the
Indochinese tiger, the Malayan tiger, the Sumatran tiger, the
Siberian tiger, and the South China tiger.
Between 1998 and 2000, nearly twenty percent of the Sumatran tiger
population was killed. The South China subspecies is also listed
among the ten most endangered animals in the world. The Siberian
tiger has recently been discovered as genetically identical with the
extinct Caspian variety, meaning that human intervention over the
past century is the only reason we ever thought they were different.
