Evolutionary Struggle and Prey Defenses
Further information: Antipredator adaptationsPredators are in an evolutionary arms race with their prey, for which advantageous mutations are constantly preserved by natural selection. In turn, predators too are subject to such selective pressure, those most successful in locating prey passing on their genes in greater number to the next generation's gene pool. Adaptations of prey that allow them to avoid protection are widespread, and this general pattern is collectively known as crypsis. Crypsis may involve temporal evasion such as nocturnality, behavioral methods such as hiding, and non-behavioral adaptations such a camouflage.
Often behavioral and passive characteristics are combined, for example a prey animal may look similar to and behave like its hunter's own predator (see mimicry).

I put on righteousness, and it clothed me; my justice was like a robe and a turban. I was eyes to the blind, and feet to the lame. I was a father to the needy, and I championed the cause of the stranger. I broke the fangs of the unrighteous, and made them drop their prey from their teeth.”
