Mojave rattlesnake
As all other rattlesnakes, the Mojave won’t hesitate to defend itself and vigorously if it is disturbed. On top of that, their venom is considered one of the most debilitating and potentially deadly in all of the North American snakes. The good news is that chances of survival are great if you seek medical attention immediately after a bite.
Cascabel
Also referred to as the Neotropical rattlesnake, Cascabel, or Crotalus durissus. Their venom is highly toxic and they are also responsible for a great deal of human fatalities.
