Which is the strongest animal of the following interms of physical strength. Arrange them in ascending order?

Cheetah (the weakest), puma, leopard, jaguar, lion, tiger (the strongest). There is no such species as 'the panther' - a panther is simply a melanistic leopard. That is, a leopard with an excess of the dark pigment melanin, resulting in an almost totally black coat (the spots will still show up against the background in certain lights).
