The western diamondback rattlesnake is a large, venomous pit viper that lives in the southwestern United States and the northern half of Mexico. It is thought to cause most snakebite deaths in northern Mexico and more snakebites in the United States than any other snake. Its diamond-shaped back markings and loud rattle make it easier to recognise, but it should always be given plenty of space.1

Nola ezagutu

Usually khaki in colour, though it may also be pinkish, brick red, yellowish blonde or white.1
A row of 23 to 45 brown or dark umber blotches runs along the back, becoming diamond-shaped towards the middle of the body.1
The tail has two to eight black bands, usually four to six, separated by white or grey.1
A grey or umber stripe runs diagonally from the eye across the side of the head, usually edged below by a white stripe.1

Askotan honekin nahasten da: The Mojave rattlesnake also has banded tail rings, but its black rings are narrow compared with the pale ones. The timber rattlesnake has no tail rings, and the black-tailed rattlesnake has a uniform black tail or indistinct rings.1

Datuak

It can go up to two years without food in the wild. In a starvation study, snakes cut their energy use by an average of 80% and still grew, as they put resources into muscle and bone.1

A juvenile was once found dead after trying to swallow a horned lizard, whose horns punctured its gullet.1

It is likely the second largest rattlesnake species, behind only its close relative the eastern diamondback rattlesnake.1

It is one of the few snake species that scavenges for food.1

Among rattlesnakes, it may be the most adaptable to towns and suburbs, and it thrives deep within developed areas.1

It is an important predator of small rodents, rabbits and birds, and it is itself eaten by coyotes, foxes, hawks and owls.1
