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.

Actually it will be a gross overestimation, and here is an example, using the biggest CBL from the Panthera cats, taken by scientists, here you can see the weights calculated (in red) and at the right the maximum weights actually recorded (in blue):
Formula use: log mass = 3.11 * log CBL - 5.38 - Van Valkeburgh (1990) - only felids.
Tiger - 342 mm. = 316.8 kg (Est.) ---- 260 kg (Real)
Lion - 355 mm. = 355.8 kg (Est.) ---- 250 kg (Real)
Jaguar - 280 mm. = 170.1 kg (Est.) ---- 148 kg (Real)
Leopard - 256 mm. = 128.7 kg (Est.) ---- 96 kg (Real)
Snow leopard - 174 mm. = 38.7 kg (Est.) ---- 52 kg (Real)
Now we can see why thise formula is not reliable, not with Panthera cats at least.
