Modern Weights and Measurements of Jaguars

[Balam]

@peter thanks for your valuable input! Lately I've been studying a lot about the ecology of cougars in different areas and I've come across some very interesting findings. For one it's very likely that Patagonia cougars are the largest of their species with mature males probability surpassing 100 kgs more often than not, as I continue to gather data I will update that thread. These cougars are feeding predominantly on guanacos and wild horses (I posted about their interactions with wild horses with more detail on the predation thread in case anyone's interested), combined with the fact that they have no competition and live in cold areas, you get the perfect recipe for large cats to occur. It'll be very interesting to see how that thread develops as we find more information.

We will also be expectant on new data on Sumatran tigers, indeed they are very understudied and I personally think some large males should have no problem surpassing 150 or even 160 kgs in weight. Likewise there are some jaguar populations that are also understudied that appear to produce large specimens, most specifically the Chaco and los Llanos. This comparatively I had made some time ago actually depicts a Chaco jaguar known as "Aries" and recently some of the biologists who tracked him said his weight should've been between 120 to 130 kg. We also have the large pugmarks of slightly above 14 cm, so we know these jaguars are also quite big. Aries and a Sumatran tiger:
