Its annual water consumption is about its body weight. In very dry areas it also absorbs water from its prey . Diamondbacks occupy dry, rocky, shrub covered terrain where they can conceal themselves in cracks in the rocks and in holes in the ground. They are found in central and western Texas, through southern New Mexico and Arizona, and into southern California. The Western diamondback has many predators , including hawks, bald eagles, roadrunners, and wild turkeys.
Diamondbacks are aggressive and easily excitable.
