Adriano weighed 130kg, not 158kg 
The largest weighed by Panthera was 148kg like Rafeal said as well.

Normal males in the Pantanal weigh 100kgs+ and normal females weigh 80kgs plus.

That makes sense about Adriano since Paulo said quite a few males he's seen are larger than he.

Its safe to say anything over 150kg for a Pantanal Jaguar should be in the same category as a 280kg Lion or Tiger or 100kg Leopard.

Thanks to Fernando Tortato, Rafeal and Epaiva.

So this is true:

The 148 kg male most likely weighed somewhere in between 133kg and 138kg.

And according to the same person, everything above 130 kg should be considered exceptional. I didn't share this becouse I knew everyone would be on top of me but since the maximum weight is indeed the 148 kg (or 133-138 kg depending how you look at it), this is worth sharing:

Quote:There are also some claimed weights of around 140-150kg reported by hunters but the reliability of these is uncertain and where some indication of stomach content is given they appear to have come from fully gorged specimens. Tony Almeida who recorded very detailed measurements of a large number of adult male jaguars hunted in the Pantanal states in his 1976 book - “no jaguar anywhere will ever weigh more than 130 kilos with empty belly, or 150 kilos gorged”. I think he may have been a tad bit too conservative here but I think barring some exceptions this is generally true. My opinion is that in a given (homogeneous) big cat population, the biggest males would be about 30% heavier than the adult male mean weight for that population with very rare exceptions. Thus at around 135kg empty stomach, the above mentioned male can certainly be considered an exceptional specimen IMO.

Also, the maximum weight sometimes stated as 350lb (~160kg) in some reference books is unsubstantiated as far as I'm aware. It appears to come from the claims of Sasha Siemel, a famous hunter who published sensationalized accounts of jaguar hunting.

Again, this is his opinion regarding their maxmium weight, I do not wish to start another discussion again since I'm not that well informed when it comes to jaguars.

Good information, which can be backed up in some reasonable way is always interesting. Especially when able to provide sources which can be checked if there is will or need for that. Sometimes information is controversial, sometimes not. Also here have been obvious misunderstandings sometimes. Those can´t be avoided in these forums. Anyway this conversation has already provided some new information, like it, that Adrian was 130 kg and not 158 kg. And in that I want to point out, that it was @Pckts who cleared that even though he was before sure, that 158 kg was valid weight. That is something what I respect, focus should for all be after all in good information, not winning every debate.

But if this debate wouldn´t have happened, we might still have here wrong information what comes to him, Adrian. Anyway that is clear, that Pantanal produce huge jaguars and Llanos is another population with potential to do the same. Most recent information points out, that today Pantanal is fantastic place for jaguars and Llanos has more challenging environment, as far as I have understood.

My personal conclusion is, that today Pantanal seems to be the place to see biggest of the big. At least more often compared to Llanos. But if new and good information comes up, there shouldn´t be any reason why not to share it :) And what I wrote is my personal opinion (based on latest postings and sources), some can agree, some disagree.
