Excellent info, but I have a question... Nothing to say as concerns forelimb girth, chest girth, skull size and so on, because, directly quantifiable, you can measure them directly (cm, inch...). But about the last parameter, "Limb robusticity", how do you evaluate it ? Is it a ratio of size, amplitude ?

Limb Robusticity (mainly referring to forelimb robusticity) is the ratio of the upper forelimb/lower forelimb.

I think of limb robustness as "mass per sq. inch. "

@Polar I'd like to try your scale "at equal weight" IMO:
Forelimb Girth (Tiger>jaguar>leopard>lion)
Chest Girth (lion>tiger>jaguar>Leopard)
Neck Girth (tiger=lion>leopard=jaguar)
Hindlimb Girth (jaguar=tiger>leopard>lion)
Skull Size (lion>tiger=jaguar>leopard)
Tail Length (Leopard>Tiger=lion>jaguar)
Limb Robusticity (Tiger>jaguar>leopard>lion)

About the skull size: usually at equal weights, lions normally have a longer skull, and tigers usually have a wider skull, so I don't get how lion is greater than tiger in total skull area (looking from top to bottom). The skull depth is about equal within both cats, so taking the total volume, the results would be based on the individual cat instead of the cat as a species (hence why I made all the cats approximate in skull length.)

Limb robusticity = "mass per square inch"? In that instance, then that is close to impossible to calculate. Different muscle fibers have differing muscle mass densities, with type-I fibers being more denser than type-II fibers, and "limb robusticity" can be measured anywhere within the forelimb and produce vastly different masses per square inch.

In all, carnivores (both caniform/feliform) share the same muscle neuron density and arrangement, FYI. Reply
