Until the 20th century there were nine subspecies of tigers.
It is estimated they numbered over 100 000 in total worldwide.
Three tiger subspecies are now extinct. These are the Caspian, Javan and Balinese tigers.
It is feared the South China tiger is now extinct as they have not been seen for years.
All remaining tiger subspecies are critically endangered. These are the Bengal (or Indian), Indo Chinese, Malay, Sumatran and Siberian.
It is currently estimated that if you put ALL the tiger subspecies together, there are perhaps about 3200 tigers now surviving in the wild.
Hunting and destruction of habitat are the main reasons for their near extinction.
Tiger populations are all on the decline.
