Crocodiles have strong immunity, which can prevent crocodiles from causing fatal infection after fighting predators in a dangerous environment. Scientists found that crocodile's powerful immune system can kill HIV, and researchers found that some protein contained in crocodile's blood can kill penicillin-resistant bacteria, such as Staphylococcus aureus.
Extended data:
Crocodiles like to live in wet areas of rivers, lakes, swamps or hills. They usually lie quietly in the water, motionless, showing only a pair of nostrils and eyes, patiently observing things on water and land.
When crocodiles find prey on the shore, they will hide themselves under the water, then swim quietly in the direction of the prey, slowly approach the target, suddenly jump out of the water while they are unprepared, bite the prey and drag it into the water to drown.
The common way for crocodiles to hunt prey is death flip, that is, they bite the prey tightly with their powerful jaws, then try their best to rotate their bodies and tear off the meat from the prey with the help of the rotating force.
Crocodiles are good at grasping the best opportunity when hunting, paying attention to getting prey with the least physical exertion, with less exercise, high absorption and utilization rate of food and strong anti-hunger ability. These characteristics help to survive when food is extremely scarce.
