Diamondback rattlesnake
The 'diamondback rattlesnake' is a very poisonous rattlesnake. Diamondbacks are found from Florida to California. The bite from a big rattlesnake can hold enough poison to kill a person. However, if the victim gets to a doctor quickly enough, he or she can usually survive. If you spend time in regions where diamondback rattlesnakes live, you should take a few precautions. People must be especially careful around caves. Rattlesnakes sometimes hibernate in caves during cool weather.
