The ridge-nosed rattlesnake is a small venomous snake with a raised ridge on the end of its nose. It lives in wooded mountains in the southwestern United States and Mexico, and it is the official state reptile of Arizona. Its bite is rarely a serious threat to people.1

Its venom is largely hemotoxic, meaning it damages blood and the tissue around the bite. Because the snake is small, it injects only small amounts of venom, so its bite is not as life-threatening as that of larger rattlesnakes. A bite can still cause pain and discomfort.1

bun da savair

Fatgs

It is the official state reptile of Arizona.1

The snake's ridge is made by upturned scales on the tip of its nose, which makes it easy to recognise.1

Although it is a rattlesnake, it gives birth to live young. The babies develop inside eggs that stay within the mother until they are born.1

Destructur da mits

Mit: Every rattlesnake bite is equally deadly.

Vardad: This species has very low venom yields, so its bite is not as life-threatening as those of larger rattlesnakes, and no deaths have been documented.1
