Western Diamond-backed Rattlesnake
Phylum: Chordata Class: Reptilia Order: Squamata Family: Viperidae Genus: Crotalus
Species: Crotalus atrox
The Western Diamond-backed Rattlesnake is one of the most notorious animals on the Regents Campus, feared for its venomous bite. It can be identified by its diamond-shaped scale patterns on its back, as its name suggests, its triangular head, and its iconic rattle. This species is aggressive and will not back down if startled or harassed. It will usually get into an “S” strike position and rattle its tail as a warning, but it does not always warn first. Always back away slowly and move far away since it can strike up to ⅔ of its body length. The rattle of the Western Diamond-backed Rattlesnake is composed of unshed scales, and this species, like other venomous snakes, has long, tubular fangs. It has hemotoxic venom which is a venom that can negatively affect the blood vessels, the blood cells, and the heart. However, rattlesnakes are a positive contributor to the environment as they help control rodent populations.
