As luck would have it, everything you ever learned from those old cowboy films appears to be true. Well, at least when it comes to venomous snakes. It turns out that after much research, Rattlesnakes are in fact the most poisonous snake in north America.

The Rattlesnake is easily identifiable by the tell-tale rattle on the end of its tail. Rattlesnakes are actually a part of the Pit Viper family, and are capable of striking out at up to 2/3rds of their body length.

The Eastern Diamondback in considered the most venomous rattlesnake species in North America. Surprisingly, juveniles are considered more dangerous than adults! This is because they are unable to control the amount of venom injected. Most species of rattlesnakes have hemotoxic venom which destroys tissue, degenerates organs and causing coagulopathy (disrupted blood clotting).

Some degree of permanent scarring is very likely in the event of a venomous bite, even with prompt, effective treatment. In extreme cases this can lead to the loss of a limb or death. Difficulty breathing, paralysis, drooling and massive haemorrhaging are also common symptoms. Thus, a rattlesnake bite is always a potentially fatal injury. Untreated rattlesnake bites, especially from larger species, are very often fatal. However, antivenin, when applied in time, reduces the death rate to less than 4%.

Venomous snakes that are found in each state

Of course, there are other venomous snakes native to North America and so the following list is designed to list the venomous snakes of each state, but should in no way be considered an authoritative list.

Let's face it, many if not most people have some anxiety about snakes and with good cause. Snakes are wild reptiles that will bite and defend themselves if threatened. For the welfare of both humans and snakes, it is best to leave them alone and to avoid contact.

In the United States there are 4 types and 20 species of venomous snakes, which cause even greater concern, due to the potential pain and lethality of being bitten.

Currently, there is at least one species of venomous snake found in every State in the U.S. with Alaska being the only exception. This will surely change as global warming continues and since snakes play such an important part in the ecosystems where they are found, it is a tragedy for them to be  killed, due to fear and ignorance.

Some basic information about snakes in general and venomous snake in particular, can go a long way in lessening our fears, while maintaining our respect for snakes and their role in nature.

My condolences to those living in Arizona - they have the most species of venomous snakes in the entire United States.
