"Its skin is so thick you aren't going to pierce it and its head is a solid mass of bone - there are no weak points. "The one thing you can do is get your fingers in its eyes - but with crocodiles, prevention is always better than cure."
Like other eaters of the Devil Fruit, he cannot swim and loses his powers when immersed in water or touched by seastone, but another unique weakness is that he loses his ability to turn into sand when he is soaked in water or is touched by something soaked in water.
Method 1: Poke the Eyes
Try to gauge, kick or poke the eyes of the animal, and there is an excellent chance that the crocodile may release you from its hold. The croc may fight you back and try not to let you go. So, you must keep repeating your attack on its eyes until it lets you go.
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.
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.
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.
Although the lion has a lot of advantages over the crocodile in terms of a fight, the crocodile would win in a fight against a lion. The crocodile is simply too large and powerful for the lion to defeat.
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.
The cause of tears in crocodilians is unclear. Apparently they hiss a lot while eating and so something to do with sinuses might be activating the tear glands. But they also shed tears just from being on land for a while, whether or not they are eating.
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.
Nile Crocodile (Crocodylus niloticus)
Although adults vary in size, most grow to reach 16.5 to almost 20 feet (roughly 5 to 6 meters) in length. 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.
A hippo would win a fight against a crocodile. Although crocodiles are large, powerful creatures, they cannot kill a fully-grown hippo. Hippos are large, round animals that are much taller than crocodiles. The only place they would be vulnerable to attack is their legs.
One of the oldest adversaries in the series, Crocodile, is known for his sand-based Suna Suna no Mi logia fruit. He's able to transform into and control sand, an ability that lets him rule over the desert kingdom of Alabasta for years.
Gouge the Eyes!
Bob Cooper, an Australian bush craft expert and survival skills instructor, agreed that “poking the eyes is the only possible way you can fight back – [crocs] have thousands of years of instinct telling them this is the only vulnerable part of their body and they need to let go.” 2.
The emetic (vomiting) reflex in a crocodilian, Crocodylus porosus, was characterised for the first time using the plant alkaloid veratrine (5 mg kg(-)(1) i.v. or i.p.) as an emetic stimulus. The latency to the onset of vomiting was 8.0+/-0.9 min (mean +/- s.e.m., N=5 animals).
Pro Tip: If you spot a croc, back away slowly and try not to make sudden movements. Splashing in water will only draw attention. If a crocodile heads your way, run away in a straight line. The myth about moving in a zig-zag motion is just that—a myth.
An unarmed person and a crocodile differ greatly in terms of their morphology, size, and sheer force. Size, defenses, and offensive capabilities will matter most in a fight between an unarmed human and a crocodile. On land, humans can outrun crocodiles, but in the water, crocodiles are considerably swifter.
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.
Did you know that the jaws of most crocodiles and alligators can be held closed with a rubber band? Their jaws close with tremendous force and sink into prey with tons of pressure (alligator = 2,980 psi [pounds per square inch] — Crocodile = 5,000 psi), but the muscles that open the jaws are weak.
Alligators have a natural fear of humans, and usually begin a quick retreat when approached by people. If you have a close encounter with an alligator a few yards away, back away slowly. It is extremely rare for wild alligators to chase people, but they can run up to 35 miles per hour for short distances on land.
During and after capture, crocodiles are often severely stressed and are easily killed or injured by inappropriate handling. This is particularly true of large crocodiles.
In fact, gators are naturally scared of humans. When faced with a human in the wild, an alligator is much more likely to fled the area than become aggressive. Now, this does not mean humans should not be cautious around gators. Feeding them will encourage the alligator to interact and will often result in an attack.
