A fully grown crocodile would win a fight against a jaguar every time. The reason is simple: jaguars couldn't muster enough power to land a fatal attack on a grown crocodile without putting themselves at tremendous risk. Jaguars prefer to hunt their prey and land a quick, fatal attack on the throat.
A male jaguar called "Scarface" attacks and kills a crocodile in the Pantanal River in Mato Grosso, Brazil.
Big cats like leopards and panthers sometimes kill and eat these big reptiles. Large snakes can also do a lot of damage to alligators and crocodiles.
Crocodiles are too large and strong for bears to overcome. A fully grown saltwater crocodile would win a fight against the largest bears. Size matters in these fights and crocodiles have that advantage. Bears are undoubtedly strong, but they've never faced anything like a crocodile to know their weaknesses.
Lions are mammals and crocodiles are reptiles. Crocodiles are larger and heavier than lions. Lions and crocodiles are both apex predators that hunt other animals using ambush tactics. However, lions are faster than crocodiles on land.
Does the Jaguar have any predators? Jaguars are known as apex predators and are at the top of the food chain meaning that they have no natural predators in the wild.
A grizzly bear would win a fight against a jaguar.
The jaguar lacks the methods of attack to bring down a grizzly bear.
Pantanal jaguars have been previously documented preying on anacondas, though bigger mammals like capybara, cattle, feral pigs, peccaries or giant anteaters (and caimans, of course) are more typical fare.
Nile Crocodile (Crocodylus niloticus)
The species easily claims the title of the most-dangerous crocodilian, since it is widely thought to be responsible for more than 300 attacks on people per year.
Jaguars fear bugs, reptiles and more.
On the whole, they tend to compete for the same prey rather than hunt each other. Crocodiles would have a greater advantage in the water if they could sneak up on an unsuspecting tiger and drag it into the water. On land, as we see in this vid, the tiger has less to fear from the croc.
Who would win in a fight: a jaguar or a tiger? While jaguars are considered to have a very powerful bite (some say the most powerful bite pound-for-pound of any big cat) and are faster than tigers, tigers are larger and stronger overall than jaguars.
Big cats – like lions, leopards and tigers – are among the few animals with enough brawn and moxie to take on a full-grown crocodilian. While these predators certainly target the occasional toothy prey, jaguars are likely the most frequent croc killers.
Green anacondas are one of the largest snakes in the world. Reports of anaconda attacks on humans are rare, but these boas can take down large prey, including jaguars.
The jaguar has the strongest bite of any big cat relative to its size. Research by Adam Hartstone-Rose and colleagues at the University of South Carolina, who compared the bite forces of nine different cat species, reveals that a jaguar's bite force is only three-quarters as strong as a tiger's bite force.
#6: Crocodiles
What is most likely to kill an elephant is the crocodile biting the elephant's trunk off. The elephant may then die as a result of not being able to eat and drink properly, or even breathe. On the other hand, a crocodile is most likely to kill a baby elephant and is most successful on its watery turf.
A crocodile would win a fight against a Komodo dragon. Crocodiles are simply too large and too powerful for a Komodo dragon to fight back against. One likely outcome would be the crocodile waiting for the Komodo dragon in the water and dragging it beneath the waves to suffer a brutal death.
A crocodile would win a fight against an unarmed human.
An average crocodile that weighs 700 pounds and measures over 10 feet long is going to be too powerful for a human to overcome.
