Baja California Rattlesnake (Crotalus enyo)

The Baja California Rattlesnake, also called Lower California rattlesnake, is a snake living in Mexico's Baja California Peninsula and the southern tip of California. 

It is relatively small, reaching up to 35 inches, and has a distinctive skin coloration that blends with its desert environments. 

Moreover, it preys mainly on rodents and lizards. Unlike most rattlesnakes, they also eat centipedes of the genus3 Scolopendra.

Prairie Rattlesnake

The Prairie Rattlesnake, or Crotalus viridis, is a venomous species in Oklahoma, Arizona, Colorado, Kansas, Idaho, Montana, Nebraska, Texas, Utah, Wyoming, and a few other states. These snakes are very noticeable in the open with oval, squarish, or hexagonal dark brown blotches along the spine and ringing tails. These snakes measure 1.5 to 5.5 feet in length and are known for preying on small mammals, lizards, and ground avians. They prefer grasslands, rocky outcrop dwellings, and sometimes even prairie dog towns; they are big fans of wintry seasonal habitats and enjoy wooded mountainous areas with moderate vegetation.

Timber Rattlesnake

The Timber Rattlesnake (Crotalus horridus) is no stranger to travelers, as it is a thick-bodied reptile with 3 to 5-foot lengths that can reach up to 6 feet at times. Timbers are recognizable by their yellowish-brown tints, dark black botches, velvet tails, and dark stripes descending and backward near the jawline. They can be discovered nearly anywhere on the eastern coast of the U.S. but also stretch to other states.

Western Diamondback Rattlesnake

Western Diamondback Rattlesnakes, or Crotalus atrox, measure 3 to 5 feet long and can grow up to 7 feet. Known to be one of the largest rattlesnakes in the western U.S., these reptiles are quite scary! Even with their heavy bodies and diamond-backed patterns, their dark cheek stripes are quite noticeable. Most commonly found in Arizona, Arkansas, California, Oklahoma, Texas, and New Mexico, these rattlesnakes are quite a sight and are most often seen around dry mountain areas and prairies, as well as rocky canyon tourist zones.

Western Pygmy Rattlesnake

Western Pygmy Rattlesnakes (Sistrurus miliarius streckeri), also called "Ground Rattlers," are red or rusty-colored reptiles that have red stripes and a rattle that is somewhat quiet or unhearable from a distance. It is unique in that it possesses nine enlarged head scales, unlike most rattlesnakes. This snake is a fierce 1 to 2-foot length creature that can be discovered around the states of Alabama, Arkansas, Louisiana, Oklahoma, Mississippi, Missouri, Kentucky, Texas, and Tennessee.

Rattlesnake Master, White Flowers

Balls of tiny flowers sit atop the tall spikes of the perennial rattlesnake master, a drought-tolerant plant with pale green summer blooms. Though it looks like a thistle, this plant is a member of the carrot family—crush the leaves to catch the familiar scent.
