Modern Weights and Measurements of Jaguars

@Pckts I think she's Abigail since I've seen her feature on a program in Korea that touched on the Jaguar ID Program, I'm sure she's really knowledgeable. She also knows about our table and our threads in the directory section. I'll keep contact to see if they can update us with better info with time.
@Balam
I will try to contact Tortato to get the confirmation on Juru's capture but after that claim I'm starting to think Globo estimated him. @Pckts Master Crawshaw returned and passed me the others measurements of the Porto Primavera jaguars. PORTO PRIMAVERA JAGUARS MEASUREMENTS. Pita male 130kg, thorax girth 114 cm, shoulder height 70,0 cm, body length 151,0 cm. Zezão male 110kg, thorax girth 99 cm, shoulder height 80,0 cm, body length 143,0 cm. Sueli female 77kg, thorax girth 96 cm, shoulder height 78,0 cm, body length 129,0 cm. Measurement method by Crawshaw's word: '' Measurements in straight line, never following the curves of the body. ''
@"Dark Jaguar" , 114 cm in in straight line for the chest girth is impressive. If you compare those measurements you can see that jaguars attain mass by becoming wider, unlike other cats who are more horizontal i.e. leopards, which is why comparing them is stupid because they're so different.
The 130 kg male also happens to be shorter, while Zezão who is 20 kg lighter was 10 cm taller. Very interesting.
@Balam
I told you in the Jaguars of Brazil thread, Jaguars are built to be like that (what you mentioned), and also I agree they kinda walk like bears, if you wanna compare a jaguar and see if its the proportionally stockier OVERALL comparing to other cat, in my opinion the best individual to use would be the Caatinga jaguars who don't get much credits. For being the smallest you will still see stockness and broadness on them meaning no matter the size or weight jaguars will still get those traits you mentioned. Many people would think a jaguar on 35kg, 40kg would be skinny but that's not the case at all when they are healthy in the wild, in Caatinga they're just miniature versions of their ''larger versions''. Even sometimes being smaller than Pumas they're still stockier and in my opinion it would still be stockier proportionately than any other cat at that size not just the Caatinga Puma. That Dark male I estimate to be 45 kg of muscles is a good example. they're built like that that's why I say it. Caatinga jaguars would be the best one to prove it. I also let it clear many times despite jaguars scientifically being related to leopard and lions, through my eyes they resemble more the tigers. both cats love water, their skulls despite the huge size difference it still got something in common with both tending to be very wide, jaguars when very angry or highly stressed out will roar incredibly reaching a ton note that is just like that of a tiger's. despite I've already shown this tiger-like roar before with Xavante cerrado male, there's another one in Pantanal that I perceived since the first time I watched that video, in case you didn't notice In the fight of Balam and Juru when both are fighting rolling down the steep, first turn up your volume then repeat the exact 44 seconds at least 7 times in a row and you'll pick the tiger-like roar. Its impressive but remember Jaguars will only reach that note when they're very very angry or highly stressed out. And back to the main point of the thread. What about Sueli what do you think of her?? I find her very impressive with only 77 kg she got a massive chest girth that is only 3 cm thinner than the 110 kg Dark male Zezão. She's also taller than Pita and speaking of him Pita was the best definition for jaguars short and broad. I will also manage to get the chest and shoulder measurements of that Porto Primavera male of 122 kg but first I will talk to Crawshaw about the 140 kg male who got ran over by vehicle. @Pckts how would you compare in sizes these 3 jaguars of Crawshaw with the jaguars of Almeida ??

A curve measurement can be added, but only measurements taken 'between pegs' reflect the true length of a cat. Head and body and tail should be measured separately. 2 - Body dimensions Try to find out in what way the chest is measured. I ask, because researchers not seldom only measure half of the chest (big cats are heavy animals) and multiply the outcome. In order to compare them to other big cats, we also need the neck, head and fore-arm circumference. 3 - Information on the size of wild jaguars in Brazil Many thanks for the measurements, Balam and Dark Jaguar. Good work. My guess is Wildfact now is one of the few public forums offering reliable (and recent) information about the size of all four big cats. Jaguarwise, you really filled a gap. 4 - Pantanal and Caatinga jaguars The information you posted shows large male Pantanal jaguars can be up to three times as heavy as large male Caatinga jaguars. This then is the effect of conditions and, most probably, population size (and density). Remarkable. 5 - Tables If you post a new table, Balam, add as many body measurements as possible (head and body length, tail length and chest- , neck- , head- and fore-arm circumference). The more we know, the better the chance to get to good conclusions. In order to prevent problems, a distinction between sources has to be made. You can, for example, post a table based on the book of T. de Almeida and one based on recent research in the Pantanal. In this way, you can get to conclusions on differences between hunters and researchers. This is necessary, because hunters tend to select large individuals, whereas researchers dart and measure every jaguar they can, including immature and/or unhealthy individuals. I'm not suggesting records of hunters are unreliable (in my opinion, quite a few compare to researchers in this respect). What I'm saying is selection has a result. Doing two tables enables you to quantify the effect. My advice is to distinguish between regions as well. In jaguars, the difference between regions seems to be quite outspoken. In order to give an example of what I mean, I added a table I posted in the tiger extinction thread in 2016. It's based on measurements in the book of the Maharajah of Cooch Behar published in 1908. As it has a lot of information (including liner notes), errors are difficult to avoid. The advantage is it offers overview:  *This image is copyright of its original author

@peter thanks for the feedback, I'm actually waiting on the Jaguar ID project as they said there were 13 to 15 jaguars capture so far in the Porto Jofre region and I'm waiting on them to provide for me the weights to add to the table. And just like you said, all this public inform on jaguars is unique to WF, not only because it is contemporary, but because it has been reviewed by the researchers themselves and is an ongoing project. I'll make sure to work on the new table once I get the new weights and I have gathered the body measurements, it may take me a while but it will get done.
@"Dark Jaguar" your assessment on the jaguars I couldn't agree more, they are called American tigers for a reason, repairs being closer to lions and leopards taxonomically, they fill the niche of the tiger in the new world. Cougars fill the niche of the leopard while we used to have our own lions during the Pleistocene. @Pckts really nice comparison of measurements from Almeida, if anything they continue to reassure that jaguars have gotten bigger since the hunting days. I'm still shocked at Joker's measurements, his chest girth is lion/tiger like even over curves, he's on his prime so I'm saying for him to be weighed this following capture season on September, I have feeling he will surprise us all.

I can't wait to hear about the captures and the best thing about JagID is that they'll be able to give you info on the individual cat and their lineage.

I've been under the assumption that tigresses usually have pugmarks of 10-12 cm in width. It would be interesting to draw the parallel because Chaco jaguars have been compared in the past to Sumatran tigers by hunters and comparing them to the data that we do have on tigers would give us a better idea of their size potential. Chaco jaguars are severely understudied and highly threatened.
Ruxu's weight according to the Jaguar ID project:
 *This image is copyright of its original author @"dark jaguar" this is why I wanted you to double check with Tortoledo.
@peter @"dark jaguar" @epaiva @Pckts, I also have some really interesting news, I was in contact with Rachael Hoogesteijn in regards to questions about his capture of Lopez and the ecology of Llanos jaguars and I'm going to share what he told me here:
 *This image is copyright of its original author In regards to the weight of Lopez  *This image is copyright of its original author "The scale with which we weight that jaguar captured in 2008 reached 300 lbs = 136 kg, but the jaguar surpassed the scale (reached the limit), with a lot of ease, so the researcher Sandra Cavalcanti, with a lot of expertise in captures and weights of jaguars, estimated him to be 148 kg, there is no way to know if he had stomach content"  *This image is copyright of its original author "In the Rosero, Apure state in the Venezuelan Llanos the brothers Velunti hunted a jaguar, the heaviest of more than a 100 they hunted and weighed 149 kg and there is a picture of the jaguar on the scale, showing his weight. 180 kg to me is a lie, I don't believe any jaguar in the Llanos weights more than 140 kg, and in the Pantanal 150 kg" then he recommended to read his book for more details.  *This image is copyright of its original author "Yes jaguars hunt wild horses when they get the chance, and there are recent cases of a jaguar that killed a very valuable tamed horse, favourite of one of the sons of the owner of La Aurora. Jaguars are big opportunists and if they have the chance of predating a horse, especially the old ones that don't run as fast, they will do it" (09-06-2020, 05:12 AM)Balam Wrote: Ruxu's weight according to the Jaguar ID project: @Balam That Jaguar ID Project size is way too big for him, that 156 kg is very strange, I am gonna need them to give more details on this capture and weight and also Panthera are the ones who really captures the jaguars. Maybe some other vets captured him before but I don't think thats the case. Tortato mentioned to me answering my question the 3 largest jaguars ever captured by Panthera.org so far were Lopez 148 kg, M02 130 kg and Adriano 130 kg and only one male weighed bellow 100 kg. And also in case he tells me the size of Gage male he could be in the 120's kg range or maybe he could be a third jaguar weighing 130 kg. Hopefully I'll find out soon Gage's size. Also I've been seen a few comparisons of Adriano and Sossego male who also weighed 130 kg and I see they're both around the same frame overall. About the wild horse predation, I always had the thought that jaguars could get the job done on wild horses. nothing surprising just the final confirmation. |
