A jaguar is strong for its size, above all in its jaws. A 2005 skull model by Wroe and colleagues gave the jaguar a bite force quotient of 137, higher than the tiger (127) or lion (112). Its canine bite came out at about 1,014 newtons, enough to bite through a skull.
How strong is a jaguar’s bite?
A newton is a unit of force. About 10 newtons equals the push of 1 kg resting on your hand. So 1,014 newtons is like having about 103 kg (228 lb) pressed down through the tips of two fangs. That is the weight of a large adult man on two points.
Nobody has measured a wild jaguar’s bite with a sensor. The number comes from a model. Wroe’s team measured dry skulls, worked out how big the jaw muscles would have been, and treated the jaw as a lever. So treat every bite figure below as a careful estimate, not a reading from a live cat.
| Animal | Body mass used in model | Canine bite force | About equal to | Bite force quotient |
|---|---|---|---|---|
| Jaguar | 83 kg (183 lb) | 1,014 N | 103 kg (228 lb) | 137 |
| Tiger | 187 kg (412 lb) | 1,525 N | 155 kg (343 lb) | 127 |
| Lion | 295 kg (650 lb) | 1,768 N | 180 kg (397 lb) | 112 |
| Cheetah | 30 kg (65 lb) | 472 N | 48 kg (106 lb) | 119 |
| Leopard | 43 kg (95 lb) | 467 N | 48 kg (105 lb) | 94 |
| Spotted hyena | 69 kg (152 lb) | 773 N | 79 kg (174 lb) | 117 |
| Brown bear | 129 kg (284 lb) | 751 N | 77 kg (169 lb) | 78 |
The last column matters most. A bite force quotient, or BFQ, compares an animal’s bite with what you would expect for its body size. An average score is 100. The jaguar’s 137 was the highest of any big cat in the study. Lions and tigers bite harder in total because they are much heavier, but the jaguar packs more bite into each kilogram.
Do jaguars have the strongest bite of any cat?
For their size, yes, according to the skull model. In raw force, no: tigers and lions beat them. You may see claims like “1,500 PSI” online. PSI measures pressure, not force, and we could not find a measured jaguar study behind any PSI figure, so we leave those numbers out.

How does a jaguar kill its prey?
Most big cats kill with a bite to the throat or by holding the prey’s muzzle. The jaguar often does something different. It is the only big cat that regularly kills by biting through the skull with its canines, says the IUCN Cat Specialist Group. Its massive head and thick canine teeth make this possible.
That bite also opens armour. Jaguars eat hard-shelled animals such as river turtles and tortoises, and they hunt caimans, which are small relatives of crocodiles. San Diego Zoo Wildlife Alliance counts more than 85 prey species, from capybaras and peccaries to deer and tapirs.
How big and heavy is a jaguar?
Jaguars are the largest cats in the Americas. San Diego Zoo gives a weight of 31 to 121 kg (70 to 249 lb) and a body length of 1.1 to 1.8 m (3.8 to 6 ft). The Cat Specialist Group gives a wider range of 36 to 148 kg (79 to 326 lb). Males are bigger than females.
Where a jaguar lives changes its size. The heaviest come from the Pantanal wetlands of Brazil, where big prey is common. Jaguars in Central America and the Amazon forest tend to be smaller. A big Pantanal male can weigh as much as two adult men.
Is a jaguar stronger than a leopard?
Jaguars and leopards look alike, but a jaguar is much heavier and stockier, with a bigger head. In the skull study, the jaguar used in the model weighed about twice as much as the leopard. Its estimated bite was more than twice as strong: 1,014 newtons against 467.
Leopards are better known for another kind of strength: hauling prey up trees. Jaguars are more at home in water, and they live on a different continent. The two never meet in the wild.
What is a jaguar not good at?
Speed is not the jaguar’s skill. San Diego Zoo notes that jaguars can run quite fast, but they rarely need to, because they stalk and ambush their prey. Our page on how fast a jaguar can run has the details.
Many strength claims you see online, such as how much a jaguar can lift or drag, have never been measured. We found no study that weighed what a jaguar can carry. If you see a number, ask where it came from.
Which animals are stronger than a jaguar?
In raw bite force, the bigger cats are. The skull model gives tigers and lions about 1.5 to 1.7 times the jaguar’s force, because they are two to three times heavier. Compare them on how strong a tiger is and how strong a lion is.
Inside its own range, a healthy adult jaguar has few rivals. Large caimans and anacondas are dangerous prey, not hunters of adult jaguars. The biggest threat to jaguars is people.
Are jaguars endangered?
The jaguar is listed as Near Threatened on the IUCN Red List (2017 assessment). The Cat Specialist Group estimates 57,000 to 64,000 jaguars in the Amazon, which is 89% of all jaguars. Many smaller groups outside the Amazon are Endangered or Critically Endangered.
Jaguars have vanished from nearly half of the land they once lived on, says Panthera. Forest clearing and conflict with cattle ranchers are the main causes.
Quick facts: jaguar strength
- Estimated canine bite: about 1,014 N, or roughly 103 kg (228 lb) of force.
- Bite force quotient: 137, the highest of the big cats in the 2005 study.
- Kills by biting through the skull more often than any other big cat.
- Weight: about 31 to 148 kg (70 to 326 lb), depending on the source and region.
- No one has measured a live wild jaguar’s bite.
Frequently asked questions
What does bite force quotient mean?
Bite force quotient, or BFQ, compares an animal's bite with the bite you would expect for its body size. An average score is 100. The jaguar scored 137 in Wroe and colleagues' 2005 skull study, so it bites much harder than you would expect for a cat of its weight.
Can a jaguar bite through a turtle shell?
Jaguars do eat river turtles and tortoises, and San Diego Zoo Wildlife Alliance says their large jaw muscles let them eat hard-shelled reptiles. How often they crack the shell rather than reach in around it has not been measured, so we can't give a figure.
Is a jaguar the same as a leopard?
No. Jaguars live in Central and South America, and leopards live in Africa and Asia. A jaguar is heavier and stockier, with a larger head, and its spots often have small dots inside. Its estimated bite is more than twice as strong as a leopard's.
How many jaguars are left in the wild?
The IUCN Cat Specialist Group estimates 57,000 to 64,000 jaguars in the Amazon, about 89% of the total. San Diego Zoo gives a much lower figure of about 10,000 for the wider Americas. Counts differ because jaguars are hard to find in thick forest.
