Arizona Black Rattlesnake

Crotalus cerberus

The Arizona Black Rattlesnake is often called a "timber rattler" because it is often found in the higher elevations/mountainous regions.

This species is said to be mild mannered, and based on severral I have seen, I'd have to agree.

What is neat about this species is that they have a lot of variability in the hue. Some animals are jet black, and others are charcoal gray. To further confuse the topic, they can change their color in short time!

All these specimens were found near Clifton Arizona along the San Franscisco River.
