Native Animals in Arizona

Arizona is rich in native wildlife, from large mammals like coyotes and cougars to smaller cactus mice and striped skunks. Some of the species that call Arizona home are found widely across the United States; however, they have many unique species.

The Gila Monster

The Gila monster (pictured above) is a venomous lizard found in northwestern Mexico up into the Southwestern United States. This lizard reaches around 60 cm long and is not known to be very quick moving; however, don’t let that fool you.

This species is the only venomous lizard in the United States and is found in many parks around the state. They prefer cooler and wetter habitats and are rarely seen in the desert.

Black-footed Ferret

Dangerous Animals in Arizona

Arizona is home to several dangerous animals, as many desert-predominant states are. At the top of the list for dangerous species are:

  • The Gila monster mentioned above is a venomous lizard that is protected in Arizona.
  • 14 different species of rattlesnakes: if you spot a rattlesnake in the Arizona landscapes, be sure to give it plenty of space.
  • The bark scorpion is the most commonly seen scorpion in Arizona and poses a significant threat to humans.
  • Arizona coral snake: a bite from this snake is two to three times more dangerous than that of a rattlesnake based on venom potency; however, since they have shorter fangs, they inject less venom than a rattlesnake.

Arizona State Animals

State amphibian: Arizona tree frog

The Arizona tree frog measures to only be slightly larger than a quarter, at about ¾ of an inch to two inches long. They are most often green with a dark black stripe on each side of their body that runs from their eyes to their back legs. They most commonly live on oak, pine, or fur trees and prefer to be above 5,000 feet in elevation. You’re most likely to spot one of these frogs in central Arizona.

State bird: Cactus wren

The Cactus wren is a relatively small species measuring between seven and eight inches long when fully grown. They are brown and have white speckling on their chest. A distinguishing feature of the bird is their white lines above each eye. They primarily live in the desert landscapes of Arizona.

State butterfly: Two-tailed swallowtail

The two-tailed swallowtail became the state butterfly for Arizona in 2001 and is considered the largest butterfly in the United States. They can only be found west of the Mississippi River and are relatively easy to spot, thanks to their bright yellow wings.

State mammal: Ringtail

The ringtail belongs to the Procyonidae family, along with raccoons and coati. The species was named the state mammal in 1986 and are very choosey about the kinds of habitats they live in. They will not live in flat open landscapes, desert landscapes, or high mountains. Therefore, if you’re looking for a ringtail in Arizona, steer clear of the desert.

Summary of Arizona’s Wild Animals

Depending on where you travel within Arizona, you’re bound to see a wide variety of wildlife. Since many of the insects and snake species found in the state are venomous, you must give them plenty of room when you do come across them. If you spot a species you cannot identify, avoid contact as it may be dangerous.
