What Are Rattlesnakes?
Rattlesnakes are venomous pit vipers that can be found in almost every state throughout the U.S. There are various species of rattlesnake, but all of them have similar colors and patterns and the highly-recognizable rattle on their tails.
According to National Geographic, rattlesnakes live from 10 to 20 years on average, grow about 5.5 feet long, and weigh up to five pounds. That said, the eastern diamondback rattlesnake can grow much larger–up to 8 feet long and nearly 35 pounds!
Rattlesnakes eat mostly small rodents, lizards, frogs and toads, and insects. They use their retractable fangs to inject their prey with venom which quickly destroys blood cells and kills the animal.
How Dangerous Are Rattlesnakes?
Of course, it’s safe to assume they could also use that venom on humans if they are trying to defend themselves. How dangerous is a rattlesnake bite to a human?
In most cases, rattlesnake venom won’t kill a person, though it can if the bite is left untreated.
The venom will begin causing tissue damage within six hours, and it will likely cause blood damage, numbness, pain, difficulty breathing, and other systemic symptoms much sooner. If not treated, the venom will continue to damage the body, eventually causing organ failure and potential death within a couple of days.
The venom may spread more quickly in young, old, or immunocompromised individuals.
The good news is, rattlesnakes usually try to avoid interacting with people and will only bite if they feel acutely threatened. And, with the proper medical treatment, most rattlesnake bite victims make a full recovery.
