Crocodiles have a bunch of neat biological adaptations that make them successful predators, all of which have made them one of evolutions big winners over the past few million years. But it’s not just their powerful jaws or tough skin… it’s also their blood!
Crocodiles have serum in their blood that acts as a powerful antibody, which means they can effectively fight off almost any bacteria or virus.
When Salties fight each other for territory or mating rights, things can get messy with open wounds and even missing limbs more common than not. Combine that with the murky, dirty water they call home, and it’s a recipe for infection but crocodiles don’t seem to ever get sick.
Medical researchers are now looking into harvesting crocodile blood to find out more about its super powers in fighting infection. With some early research suggesting that crocodile serum could even be used to fight off the deadly HIV virus.
