There are four forms of venomous snakes within us. whereas there are many various species within these sorts (for example there are many different species of rattlesnakes across the States), all venomous snakes that are native to us belong to 1 of those four families.
Rattlesnakes. These are out and away and away the foremost common kind of venomous snake in the United States and may be found altogether in forty-seven states that have venomous snakes (Maine, Hawaii, and AK are the three that have none). rattler rattlesnakes can grow as long as 7 feet long or more, whereas smaller cousins just like the pygmy pit viper seldom hit even twenty inches. These are a number of the deadliest snakes altogether of North America and want to be revered and left alone in the wild.
Coral snakes. There are three species of coral snake in the United States, all of that are found in southern states. they'll be found from North Carolina, on south on the coast to Arizona. Coral snakes are different since they don't have identical kinds of fangs to pit vipers like the rattlesnake, copperhead, or water moccasin. This doesn't create them any less dangerous, however, as they're still deadly if the venom is injected into the skin.
Copperheads. this can be an "Eastern" snake because it is found principally within the south, Texas, the lower Midwest, and in the Appalachians of the northeast. These snakes are typically bold, which may cause encounters with individuals and accidental bites. they're terribly recognizable with a definite sepia from that they get their name.
Water Moccasins. conjointly called "cottonmouths," these snakes are famous for being dangerous and to a fault aggressive in offensive people. usually found within the geographic region and lower Midwest, these are some snakes you don't wish to mess with. they're all black with bright white mouths.
