Modern Weights and Measurements of Jaguars

Thanks for your questions. The 142 kg male was a mistake where Lopez was included twice. This happened during a very early stage of the data collection process when we were starting to gather all the information and sometimes some animals would be mentioned with different names or in different sources which caused some confusion. All this has since been rectified in the official publicized Google docs file, which should be the only link to reference the data compilation at this point since there is where you'll find the most up-to-date information with recent captures and developments.

I don't know which 155 kg jaguar you are referring to as we never included that figure in the data set. Are you referring to the 158 kg specimen quoted by Seymour? That specimen has as original source jaguar hunter Sasha Siemel. That jaguar nicknamed "Assesino" was killed by Siemel in the 20th century and was, according to him, the largest jaguar he had ever seen. This jaguar was never weighed but he estimated him to have been at least 350 lbs. There are no photos of the animal and the skull was sold off by his family years later, so no records were kept either unfortunately.

There is a reliable record of a non-obese 158 kg captive jaguar from Florida that came from someone who had access to the cat and its keepers who stated it was weighed regularly on a scale, but this wasn't a wild specimen so it can't be included in the table. Only 2 specimens have been weighed surpassing 140 kg in weight on modern scientific records so far, those are Lopez and Joker.

We may get more large males of similar size recorded when Onçafari resumes its capture campaigns in the southern Pantanal, it's a matter of patience but also of appreciating all jaguars in all their sizes. Reply
