There is a strong evolutionary pressure for prey animals to avoid predators through camouflage, and for predators to be able to detect camouflaged prey. There can be a self-perpetuating coevolution, in the shape of an evolutionary arms race, between the perceptive abilities of animals attempting to detect the cryptic animal and the cryptic characteristics of the hiding species.

This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals with higher longevities and slow growth rates. [2]
The U.S. Fish and Wildlife Service has proposed new protections for giraffes, saying their populations are threatened by poaching, habitat loss and climate change. Giraffes need endangered species ...
