The Sidewinder gets its name from the unique way it moves sideways, leaving a temporary trail in the desert sands.
The Sidewinder is a type of rattlesnake and is sometimes referred to as the sidewidner rattlesnake or horned rattlesnake. This name refers to the "horns" above the snake's eyes which may have developed to help protect its eyes from the desert sand.
Sidewinders are venomous, but they only produce an average of 33mg per bite, so these are rarely fatal to humans. Their venom is less fatal than other rattlesnakes.
The Sidewinder has lived up to 17 years in captivity.
They are primarily nocturnal creatures, helping the snake to avoid the desert heat.
