In what groups we can divide the Bengal Tiger?

[Pantherinae]

I far from an expert on this regarding tigers, but I have had the same thoughts and questions about lions after watching them for several years and seeing how different they are from region to region, going from Krüger to west and eastern populations all are different some much more so than others. 

Here's my personal view on the Tigers: 

Terrai seems to me very much like the Assam tigers probably because they share very similar habits living in marsh/wetlands lands with high grass or dense forests they seem to have a huge upper body unlike any cat's today, also are they probably of the slowest cats because of their massive weight, but that's because they don't need to be fast. Because with such great cover they can grab prey by pouncing on them from extreamly short distance, and that they are surrounded by large prey that they can and have adapted to prey on, and the terrain makes that way easier for an probably less agile version of the Bengal tiger.

The Ranthambore Tigers are a tough one, where do we put them? It's a unique version imo. Very big although not as massive muscles in their front quarters as others, but they are very long, tall and overall extreamly solid. And they don't hunt bovines so they, are hunting mostly fast prey like deer (sambar and Axis) and Nilgai, so they are probably the fastest of the tigers.

Central tigers are the most overall solid tigers imo, they have massive heads with big necks, are long and tall, and are overall very muscular tigers, with some being larger than others, with Kanha and Pench probably having the biggest ones in Central India, some big individuals in Tadoba and Bandhavgarh etc, but on average they seem a little bigger, they have lighter orange fur. And are adapted to hunt fast both small to large prey from langur and axis up to gaur in size and need to be both fast, agile and strong.

South Indian tigers: much of the same as with the central Indan tigers, small to large prey and needs to be very fast, agile and strong as they tackle much of the same prey, and I disagree with the popular saying they they are smaller, there are several individuals from especially Bandipur that are huge, but probably smaller on average.. But they have smaller heads. Reply
