Mojave rattlesnake

The Mojave rattlesnake is a venomous species found in the deserts of the southwestern United States and central Mexico. It is perhaps best known for its potent venom. The Mojave rattlesnake, Crotalus scutulatus, is the most dangerous snake in the United States. Unlike most other rattlesnakes species, California specimens possess highly neurotoxic venom in addition to hemotoxins. This deadly cocktail of toxins attack both nerve endings, leading to paralysis and respiratory failure, as well as massive destruction of tissue and blood cells.

This rattlesnake species averages between 3.25' (100 cm) and 4.5' (137 cm) in length. Their color varies with the terrain, ranging from shades of brown to pale green. Their frequent green hue, has led to their being called "Mojave greens" in some areas of the U.S. This snake is not considered endangered and is found in a fairly wide distribution throughout the southwestern U.S. in good numbers.

The Mojave rattlesnake is often found in close proximity to large and growing population centers in southern California and therefore may be encountered more frequently by humans then other species. They have a reputation for being fairly aggressive, although this is based largely on anecdotal information, rather than scientific evidence. Like most rattlesnakes they will defend themselves rigorously, against perceived threats such as handling, or when disturbed.

The Mojave rattlesnake is widely considered one of the most dangerous and venomous snakes of the Western Hemisphere. The bite from a Mojave rattlesnake is a serious medical emergency and is potentially life threatening. A snake to leave alone and avoid, the Mojave earns first place on my list of the U.S. most dangerous snakes.
