It would be great if you post the information of Sumatran Tigers bite force.

Bite force of Sumatrans and Jags

Sumatran tigers have higher bite force than Jaguars, this was given in the Christiansen and Wroe study on canine morphology.
Canines of Sumatran tigers are longer and had higher bending strength, meaning their canines are longer and stronger than the jaguars.

When you compare the skulls, the Sumatran tiger skulls are bigger and more massive than the jaguars.

In the Pantanal region of Brazil predation of Caiman (Caiman yacare) by Jaguars provide a unique opportunity test predictions regarding prey selection, They used living animals captured to predict the BM (Kg) in from body and head measurements by general linear regression. In atached table can be seen estimated body mass of 22 predated Caiman, Caiman yacare. They examined patterns of Jaguar predation on Caiman in Southern Pantanal, Brazil. Body mass in kilograms was predicted by linear regression from dorsal cranial length (DCL) measured from skulls of Caiman predated by Jaguars collected from 2003 to 2008.

Jaguar takes out hefty caiman in dramatic series of photographs

*This image is copyright of its original author

BY ETHAN SHAW SEPTEMBER 30 2017


Jaguars are the biggest and burliest of the New World's big cats, and rank third behind lions and tigers among the largest in the world. Packed in muscle and wielding some of the strongest jaws for their size in the cat family, they sit comfortably atop the Neotropical food web, and while elusive as heck, they sometimes permit human beings to witness them fulfil their trophic status in dramatic fashion.

Photographer Chris Brunskill caught the sequence of a lifetime along the Three Brothers River (Rio Tres Irmaos) in the Brazilian Pantanal earlier this week: a jaguar taking down what Brunskill called in a Facebook post "the biggest jacare caiman I have ever seen during my time on the river in Pantanal".



*This image is copyright of its original author


The shoreline struggle between big cat and (big) caiman lasted some 20 minutes, but this wasn't exactly a tit-for-tat battle: it was a predatory exercise by a born-and-bred crocodilian-hunter.
Brunskill's epic photos show the jaguar administering some fierce throat chokeholds, but the photographer reported on Facebook that the killing bite – in typical jaguar fashion – was delivered to the back of the caiman's skull. This is how these low-slung, rosette-splattered, heavy-headed bruisers commonly dispatch larger prey, from capybaras to the odd black bear.

In his post, Brunskill said the jaguar, which he tracked for roughly an hour before it nabbed its reptilian repast, had made an unsuccessful sortie upon a group of capybara (the biggest rodents on earth) not long before.

A few jaguar attacks on caimans have previously been caught on film, including this well-publicised ambush of an oblivious mudbank-basking victim

And then there's this one, which captures a jaguar's diving leap and underwater strike to wrestle out its quarry:




Brunskill's amazing image series, though, may just take the cake in terms of the relative size of the jaguar's scaly saurian meal, which the carnivore nonetheless manages to haul off into the tangles quite handily.                       
It's a highly respectable display of feline strength and moxie, and a reminder that large crocodilians – for all their obvious power and a 250-million-year-long track record as ecological heavy-hitters – aren't immune from periodic predation. Big cats are among the few creatures capable of tackling a full-grown crocodilian under the right circumstances (and the reverse is true as well). While tigers and lions certainly hunt these formidable beasts on occasion, the jaguar overall is probably the most frequent croc-stalker of the bunch. 
Caimans, after all, aren't incidental meals for jaguars, but rather linchpin prey items in many areas of the cats' range, including the flooded bottomland rainforests of the Amazon Basin and the great marshlands of the Pantanal, among the planet's biggest wetlands.Studies in the Pantanal have revealed that jaguars target caimans across a broad size range. And these recent snapshots certainly prove they aren't afraid to pounce upon some genuine honkers.

Incredible pictures very powerful Jaguar, it hunted a huge Yacare caiman at least 2,50 mt long.

Dramatic moment a jaguar and a caiman fight to death captured in incredible pics
DRAMATIC picture show when a fearsome big cat wrestled with the reptile for around 20 minutes in a struggle witnessed by a wildlife photographer.

THESE astonishing images capture the dramatic moment a jaguar and a caiman fought to death in a Brazilian jungle.
The fearsome big cat wrestled with the reptile for around 20 minutes in a struggle witnessed by wildlife photographer Chris Brunskill, reports The Sun.
This battle happened on Tuesday on the Three Brothers River in Mato Grosso, Brazil.
Jaguars hunt the small to medium-sized crocodiles — but rarely is such a clash photographed.
Snapper Chris rushed to the area after he learned the majestic cat was spotted near Corixo de Camindo.

In a Facebook post, he wrote: “Over the next hour we followed the cat and watched at close range as she charged unsuccessfully on a small group of capybara.
“Moments later she was walking through an open stretch of water when she pounced on the biggest yacare caiman I have ever seen during all my time on the river in Pantanal.

“After a long struggle, she immobilised the giant reptile with the trademark jaguar bite to the back of the skull, and then dragged the huge carcass for over twenty minutes across an open beach into thick cover.
“During the struggle I shot an incredible variety of pictures, almost 50GB in total, of a predation (animal attack) sequence I have been obsessed with since I first visited this magical place over five years ago.”

In July last year a 99 kilogram jaguar took down another caiman in the South American country.
Around 30 years ago, the caimans faced an even bigger threat due to a lucrative market for crocodile leather.
“Nobody can say for sure how many yacares were slaughtered, but it would have run well into the millions,” Cleber Alho, a Brazilian conservation biologist, told National Geographic.
After Brazil’s government cracked down on poaching and following a 1992 global ban on trading crocodile skins, the creatures flourished. Now as many as 10 million live in the wetlands.

Jaguars are most fearsome cat in the world. They are hunting big size caiman as well which I think equivalent to Indian mugger.
Also this thread is one of the best thread on WidFact. Keep up the good work guys.

Does anybody know how big Arizona jaguars are? There is a very impressive account about jaguar predation which look reliable but look almost too good to be true. Unless those jaguars are bigger than I think...

@Richardrli
It was originally posted on carnivora iirc : https://www.smithsonianmag.com/science-n...180960443/

It's about jaguar predation on a sow black bear.

''Removing the bear skull from its zip-lock bag, he shows it to Neils, an expert on black bears from her years studying them in Florida. “This was a young adult female about 230 pounds,” she says. Bugbee then removes the suspected jaguar scat, spritzes it with water, and reseals it in the plastic bag. He waits for an hour and then hides the moistened scat among the cactuses in the front yard.''

The size of the jaguar is unclear : ''He was 120 pounds when he arrived. Now he’s a big adult male in his prime. He’s grown into his name.''

Erm, no... Muggars are way larger than most caiman varieties.

The largest ones, the black caiman (Melanosuchus niger), which can grow more than 5 m (16 ft) in length and weigh up to 1,100 kg (2,400 lb) are as large...& heavier maybe.

I have a query... Is "Arizona Jaguar" an accepted concept?
Because Arizona has only transient males today, who are probably Mexican jaguars. 


Were the jaguars of California to Florida a separate, now-extinct subspecies?
