 Predators are physically distinguished from humans by their greater height, arthropod-like mandibles and long, hair-like appendages on their heads that are set into their skulls (popularly perceived as "dreadlocks").Their bodies are resilient to damage, capable of recovering from multiple gunshot wounds and radiation doses that would prove fatal to humans.Their wounds do, however, require medical attention and they incorporate a portable surgical kit in their armor for this purpose.
