Sumatran tiger a separate species
Sumatran tiger a separate species An American Museum of Natural History research
project suggests that the Sumatran tiger is a separate species from
other tigers. DNA comparison of different types of tigers was used
to make this finding. Sumatran tigers have a very small population,
and researchers say that finding that they are a separate species
means that extra effort needs to be made to save them. There are
only about 400 or 500 Sumatran tigers left in the wild. They are
the smallest tigers and weigh only 100 to 140 kilograms.
