Modern Weights and Measurements of Jaguars

'A MORPHOLOGICAL COMPARISON OF JAGUARS AND PUMAS IN SOUTHERN MEXICO' (J.A. de la Torre and M. Rivero, 2017 - in: Therya, Vol. 8, no. 2) 

The sample is a bit small (jaguars: 2♂ and 3♀ - pumas: 8♂ and 3♀), but the article again shows that two cats living in close proximity tend to develop into two very different species using a region in different ways. In most cases, the smaller of the two tends to get smaller. When the competition disappears, the opposite is seen.

As to morphology. The 2 male jaguars averaged 52,5 kg., whereas the 8 male pumas averaged 31,25 kg. In females (34,33 kg. and 21,33 kg.), the difference between both species is as outspoken as in males. Although pumas, as a result of a longer tail, are a trifle longer (referring to total length), jaguars are about 4 inches longer in head and body. They also have longer heads and longer and more robust upper canines.  

Southern Mexico could have the smallest jaguars and pumas I know of. They're definitely smaller than in Surinam.
