Amelanistic rattlesnake
This Texas diamondback rattlesnake (Crotalus atrox) lacks melanophores containing the pigments black and brown due to a gene malfunction. The condition is called amelanism. The faint pattern is formed by carotenoid pigments which are unaffected by amelanism. The condition is sometimes confused with albinism but, in that case the body would be a patternless white and the eyes would be pink. While specimens are prized by zoos and collectors, the abnormality would unlikely to be an advantage in the wild and the snake would probably not survive. Without camouflage patterning it would be harder to hunt or avoid attack and, less obviously, successful courtship and mating may be more difficult.
