QUESTION: Will a bite from this snake kill you?
Obviously, the snake in this picture is a rattlesnake; the issue is what type of rattlesnake. All rattlesnakes in North America produce a hemotoxic venom that destroys tissue/blood which makes them all potentially lethal without proper medical attention.
However, the Mojave Rattlesnake pictured above is especially lethal due to its combination of neurotoxic AND hemotoxic venom. The presynaptic neurotoxin produced by the mojave attack the nervous system, sometimes affecting the bite victims ability to swallow or breath.
