There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

True, Pantanal jaguars are some of the biggest at 95 kg. But I was referring to jaguars (general), and Pantanal jaguars are on the higher end of the size range.
I never said they couldn't ambush and kill big caiman. I said the majority of the time they go for smaller or similar sized caiman.
1: They're well over 95kg, that's a small male Jaguar in the Pantanal
2: and technically you said they were "overrated".
3: We're talking about where Jaguar and Caiman coexist and in Places like Los Llanos and the Pantanal, it's no surprise that Jaguars thrive and are the largest on earth, this is directly due to the fact that Caiman thrive there as well. Like I've been saying, there is no Big Cat more adept to prey on Crocodilians than the Jaguar, it's what they're built for.
4: And there is no "majority of time," like with all animals, the largest of Caiman make up the smallest minority but that never stops a Jaguar from preying on them when they can catch them. It's all a matter of opportunity, big cats take what they can get. Lions and Tigers prefer larger prey but that doesn't stop them from taking Chital/Impala or youngsters when the opportunity is there.
5: That doesnt somehow make one over or underrated though.
1: Source for Pantanal jaguars averaging over 95 kg? Just about everywhere I've seen states 95 kg average for males including GuateGojira himself.
2: What does that have to do with the prey preference of jaguars? I was referring to jaguars being overrated in their ability to kill very big crocodiles (you gotta admit, a jaguar's being overrated if someone's backing it against an American alligator, American crocodile, black caiman, or Orinoco crocodile. Besides, I never said they could not. I said they were overrated in terms of it).
3: Never denied that
4: Exactly, it's rare for jaguars to prey on very big caiman. I never said they couldn't but it is very rare.
5: Like I said, wrong context
1: Rafeal Hoogestejin Fernando Tortatto both run the Panthera capture project,
their averages are 100kg. You can see direct correspondence from them posted on numerous pages in the verified jaguar weights thread and the edge of extinction Jaguars thread.
But again, 100kg is small.
They have weights of many over 130kg and even over 148kg almost empty.
The 97kg average is from Almeidas book only and even he knew of 130kg plus Jaguars and Skulls over 21" scores. He also measured from all over the Pantanal and other areas as well and he did so during a time of immense human pressure on Jaguar and Caiman. In the meeting of the 2 rivers, that is where you have the largest cats and caimans around and that's not where Almeida did most of his hunting.
Another good IG page to follow for Southern Pantanal weights is called Oncafari, they too have a few over 130kgs but slightly smaller than the North.
2: In regards to someone backing it over A Black Caiman or American Alligator, I have no knowledge of that and no one here is making that claim.
3: Lastly, it's not rare for them to prey on large Caiman, I just posted numerous accounts of it occurring.
1: I never said they couldn't exceed 95 kg. But 130-148 kg jaguars, while they do exist, are by no means the average
2: I told you, that was on The World of Animals. Not here.
3: As I said before, of all those nonstaged accounts, the caiman looked similar to or smaller in weight than the jaguars. Maybe that's just what I'm seeing, but none of them seemed THAT big in weight terms.
The average weight for jaguar in the Pantanal is way above 100 kg, probably closer to 115 kg. There are multiple new weights posted in the jaguar predation thread to exemplify this, post #230 has a compilation of all of them.
If you are trying to go by the outdated hunting records of Almeida 40 years ago, then your information would be highly inaccurate. For one, according to his records Llanos jaguars would take the spot as the largest jaguars because the average he achieved for them was higher, but those of us who follow and study these jaguars know that jaguars from los Llanos are in fact smaller of average than Pantanal ones and are more closer to Cerrado jaguars in weight, although the occasional large male of 130+ kg can definitely occur.
Also, your claim that jaguars are "overrated" in their interactions with crocodilians could easily be dismissed by the scientific data we have that states that Holocene jaguars developed a specialized morphology to hunt large reptilian prey on the absence of large ungulates, unlike other felids in Africa or Asia. Jaguars have the strongest jaws lb for lb and the widest zygomatic cranial width proportionally of any felid because they need a powerful bite to break through the armor and skull of the hardy animals they prey on.
To answer the question of this thread, I noticed that the feat of the 3.8 meter black caiman was already posted. Personally, I doubt even the largest jaguar could succesful kill a 300+ kg American or Orinoco prime crocodile, or a black caiman for that matter, unless the rumble occurs within land then a big male might have a chance if it can position itself above the crocodile and target the back of the neck behind the skull. Other than that, large crocodilians are too much for any cat, including lions and tigers.
