Snakes in Arizona

Arizona has over 20 venomous snakes, most of which are part of the rattlesnake group. The Mojave rattlesnake is the deadliest in the state. However, increased fatalities are accounted to the western diamondback rattlesnake. There are also king snakes, garter snakes, and coral snakes. One could barely find actual water snakes in Arizona. Some of them like the checkered garter snake, Mexican garter snake, and black-necked garter snake are semi-aquatic.

Most snakes in Arizona come out when it is warm enough between April and October. During summer, you would mainly spot them at night. One could even catch sight of them during spring and fall and on a warm winter day.

The ridged-rose rattlesnake, a venomous pit viper, is the state reptile of Arizona.
