Grand Canyon Rattlesnake (Crotalus oreganus abyssus)

Grand Canyon Rattlesnake, also called the Pink Rattlesnake, inhabits the Arizona and Utah states of the USA. Its colors, ranging from pink to grey, resemble the surrounding rocks, allowing it to blend into the Grand Canyon's stunning landscape. 

Unlike most nocturnal rattlesnakes, the Grand Canyon Rattlesnake prefers the cooler daylight hours to hunt for small mammals such as mice and rats. However, it may occasionally prey on birds.
