Due to the large size and highly aggressive nature of these apex predators, adult crocodiles have very few predators within their natural environments with the exception of occasional takings by big cats such as lions, jaguars, and tigers.
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. There are countless videos showing snakes wrapped around gators and crocodiles.
Legally, crocodiles can be shot in the head, and if they are below 2m in length, they can be bludgeoned to death with a hammer or other tool. Almost all crocodiles raised for leather are killed before they are old enough to reach 2m.
In conclusion, I think that the only animal a crocodile genuinely fears is the hippo. Smaller crocodiles may fear larger ones due to risk of cannibalism but that's pretty explainable. Animals that a crocodile may avoid due to unnecessary risk include elephants, lions, and rhinos.
"Lions are wary of crocodiles and will generally avoid the water to stay away from crocs," writes NatGeo TV.
Although a crocodile has an amazingly powerful bite down it has surprisingly weak opening muscles - so much so their jaw can usually be held shut by a rubber band or bare hands.
Never provoke, harass or interfere with crocodiles, even small ones. Never feed crocodiles — it is illegal and dangerous. Be extra vigilant around water at night and during the breeding season from September to April. Avoid approaching the edge of the water and don't paddle or wade at the edge of the water.
Crocodiles can run very fast when they are about to attack. So, skip those "running in zigzag motion" advice and run in a straight line as fast as you can. The goal is to get away from the croc as far as possible.
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.
But most large crocs can run between 15 to 22 mph (24-35 km/h). Can a human outrun a crocodile? In most cases, yes. In fact, there are limited instances where a crocodile would ever chase a human.
Now, some people may ask, “what if the human rolls the alligator on its stomach?” Even in that case, humans lack the power to kill a fully grown alligator. Without so much as a rock, the human won't be able to bludgeon, bite, or strangle the gator to death.

This was an extraordinary occurrence. It is not the first instance an elephant has been shown in the wild killing a crocodile. There have been times in the past when the crocodile overpowers a full-grown elephant.
They are extremely difficult to approach on foot to within a reasonable shooting distance. This "big lizard" is extremely hard to kill quickly and cleanly. The first shot on the croc must be carefully placed to anchor him because if he is allowed to retreat to the water, the trophy is surely lost.
Clearly, the best thing is not to be attacked in the first place: Don't swim in any rivers that might have crocodiles in them. If you must swim, avoid backwaters and inlets where crocodiles lie in wait.
Keep a safe distance if you see a crocodile. Be aware that crocodiles often will bask with an open mouth to regulate their body temperature, and there's no cause for concern if you see this behavior. Swim only in designated swimming areas and only during daylight hours. Crocodiles are most active between dusk and dawn.
It's just that you don't get that fishy smell you'd expect, even when you scoop a chunk of fish out of their stomach. I've often had my hand right at the esophagus, because they have a waterproof flap in the back of their mouth that you have to hold down when you put the stomach scoop in. And they don't stink.
Bears have better senses than crocodiles, and they are stronger overall than crocodiles. Also, bears are faster on land than crocodiles. Both creatures rely on their bites to finish off enemies. Of course, their bodies are very different as well.
The International Union for Conservation of Nature (IUCN), which is famous for its Red List that characterizes the conservation status of various species, suggests that crocodilians strike out at human beings for four reasons: (1) they're hungry, (2) they're defending their territory, (3) they're defending their young, ...
Researchers found that the small, spotted bumps that cover the skin of crocodiles and alligators are chock full of nerve endings that are exquisitely sensitive to pressure and vibration.
A crocodile would win a fight against a gorilla. Most of the fights would begin in or near water, and a gorilla doesn't stand a chance in that scenario. If a crocodile bit and dragged the gorilla into the water, then it's a simple victory. The two creatures might meet each other on land, though.
Research shows that they do. However, their emotions are not the same as humans. We may anthropomorphize crocodiles and snakes in certain ways, but they are not conniving evil beasts. They feel fear and anxiety and contentedness, even if it is in their own way.
