Species With Immune Systems Stronger Than Any Other Animal
Alligators
Lurking in murky swamps filled with harmful bacteria, alligators possess blood that acts like natural antibiotics. Their immune proteins kill dangerous germs including antibiotic resistant superbugs that threaten human health.
Researchers discovered alligator blood destroys HIV and numerous bacteria in laboratory tests. Despite frequent injuries from fighting and hunting, these reptiles rarely suffer infections, thriving in environments that would sicken most animals immediately.
