Size comparisons

[Luipaard]

@Shadow I think I have the right to answer despite being off-topic. @Pckts & @BorneanTiger 

"Across their range, jaguars exhibit up to 100% variation in body mass (Sunquist and Sunquist, 2002) and this is likely to impact their hunting decisions, with the smallest forms being more similar to leopards in the size of their prey. For example, Hoogesteijn and Mondolfi (1996) found that floodplain jaguars were significantly larger [body mass: Llanos = 104.5 kg (males), 66.9 kg (females) and Pantanal = 99.5 kg (males), 76.7 kg (females)] than forest jaguars [body mass: Amazon = 83.6 kg (males), no data for femalesand Central American = 56.1 kg (males), 41.4 kg (females)]. This variability was also reflected in the diet of the populations, with the forest jaguars having a significantly lower mean weight of vertebrate prey at 5.8 kg, compared to 89 kg (including livestock) for floodplain jaguars (Hoogesteijn and Mondolfi,1996)"

The difference is marginal though, as can be seen when looking at skull measurements:

The title of 'largest jaguars' belongs to the Venezuelan jaguars.

Another example:

"Manaus, AM - A 72-kilogram jaguar caught in a snare trap surprised researchers at the Mamirauá Institute. In ten years of working in the Sustainable Development Reserve, they had not yet found such a large animal. Okay that in other regions, jaguars can reach almost twice this size. But it is that the jaguars of the Amazonian floodplain are much smaller than their relatives of the Pantanal and mainly of the Venezuelan cerrado. 

Galego, as the male was baptized, is 11 kilos more than the heaviest jaguar that the researchers had registered so far and 17 more than the average of the males captured in the RDS, according to what he told the site of the institution the researcher Emiliano Esterci Ramalho, from the Mamirauá Institute. The beast now carries a telemetry collar and is followed via satellite by the researchers. 

Biologist Rogério Fonseca, a professor at the Federal University of Amazonas, agrees that it is a large animal by Amazonian floodplain standards. He studies the interaction between jaguars and human populations and says that in the Pantanal, the jaguars reach 100 kilos. But the largest are in the Venezuelan cerrado. The biggest ever recorded was 140 KG, according to him." Reply
