There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I think is fair to say that there is more intraespecific variation between the Bengal population than between the Amur population.
The smallest Amur specimens (Korea?) that I know are no smaller than the Indochinese tigers, while the smallest Bengal specimens (The Sundarbans) are of the same size than the small Balinese tigers.
In captivity, it seems that Amur tigers are in fact the largest cats overall in all the senses, but in the wild, Bengal reach the same sizes (length and height) and now even a much higher body mass.
