You can learn more about the mohave rattlesnake here.ģ. This snake is widely distributed within its range and is often thought to be more dangerous than other species on this list due to the amount of venom they produce and deliver in a bite. The mohave rattlesnake is a medium to large sized rattlesnake that inhabits much of the semi-desert grasslands and scrublands that exist in Arizona, Southern California, New Mexico, West Texas, and down in Mexico.

However only the desert massasauga is found in Arizona, and only in a portion of the Southeastern corner of the state. There are 3 subspecies of the massasauga rattlesnake: the eastern, western, and desert massasauga. Scientific name: Sistrurus catenatus edwardsii.Desert massasauga rattlesnake image credit: Duncan Sydney Rowe Now let’s take a closer look at the rattlesnakes of Arizona. The 14 species of rattlesnakes found in Arizona are the desert massasauga rattlesnake, mohave rattlesnake, sidewinder rattlesnake, grand canyon rattlesnake, Arizona black rattlesnake, great basin rattlesnake, tiger rattlesnake, prairie rattlesnake, northern blacktail rattlesnake, Arizona ridge-nosed rattlesnake, southwestern speckled rattlesnake, western diamondback rattlesnake, twin-spotted rattlesnake, and the banded rock rattlesnake. These rattles are actually made up of sections keratin (what our finger nails are made of) spaced apart just right so that when they shake the end of their tails, you get the rattle sound that warns off predators. They get their name from the “rattles” they have on the ends of their tails. Rattlesnakes are venomous snakes in the viper family, and are only found in the Americas. Which leads us to the topic of this article, the rattlesnakes in Arizona. That’s more rattlesnake species than any other state. Based on my findings, 14 of these species of rattlesnakes can be found in the state of Arizona. Let’s see which are the safest states concerning venomous snakes in America.There are a total of 36 identified species of rattlesnakes, and they can be found in most U.S. After picking states with no or least poisonous snakes, we have compared the data with governmental and wildlife sources for each of these states in order to rank the states on our list. Poisonous snakes that inhabit these states do not belong to the most venomous snakes in America, and are usually quite rare, and also encounters with humans are very uncommon.įor the information on states with no or least poisonous snakes in America, we have consulted primarily Venombyte and Cobras sites. During the winter, especially in colder areas, snakes hibernate in the underground tunnels or some other protected shelters. However, snakes are adaptable creatures that inhabit most variable ecosystems, from deserts, forests, swamps, meadows to the open seas. That is to be expected, because snakes usually prefer warmer climates, being cold blooded animals that cannot produce heat themselves to warm their bodies. So, according to that, states with no or least venomous snakes in America also tend to be the northernmost. That is also the case in the US, the northern belt has less than 5 poisonous animals per state, and the figure gradually grows towards the south, where Arizona has the most poisonous animals (around 30 species). Venomous animals, in general, are often being met in warmer climates.
