Western diamondbacks are found in California, Arizona, New Mexico, Texas, Oklahoma and Arkansas.
The Arizona Diamondbacks are a professional baseball team based in Phoenix, Arizona. The name Diamondbacks came from the Western Diamondback, a rattlesnake native to the State of Arizona.
Texas Rattlesnakes:Western massasauga(Sistrurus catenatus tergeminus), light gray, with brown oval blotches along the middle of the back and smaller blotches along each side. They are two feet in length and found through the middle of the state in grasslands, marshy and swampy areas.Desert massasauga (S.c. edwardsii), lighter in color than the western massasauga, smaller and more slender. Found in the Trans-Pecos, western Panhandle and the lower Rio Grande Valley.Western diamondback (Crotalus atrox), Brown, diamond-shaped markings along the middle of the back and alternating black and white rings on the tail. Averages 3 1/2 to 4-1/2 feet in length, and can reach seven feet. This is the most common and widespread venomous snake in Texas, found in all but the easternmost part of the state.Timber rattlesnake (Crotalus horridus) also known as Canebrake rattlesnake is a large, heavy-bodied snake averaging 4-1/2 feet. Brown or tan with wide, dark crossbands. Tail is entirely black. Found in the eastern third of the state in wooded areas in wet bottomlands.Mottled Rock rattlesnake (Crotalus lepidus) is light bream or pink background with widely spaced, dark crossbands and mottled areas between the crossbands. Small and slender with an average length of about two feet. Found in the mountainous areas of West Texas.Banded Rock rattlesnake (C.l. klauberi)Similar to the mottled rock rattlesnake, but darker greenish-gray in color. Found only in the extreme western tip of Texas.Blacktail rattlesnake (Crotalus molossus) is gray to olive green with dark blotches along the back and a black tail. Averaging a length of 3-1/2 feet, it is found from Central Texas throughout most of West Texas in bushes and on rocky ledges.Mojave rattlesnake (Crotalus scutulatus) is similar to the western diamondback in markings, but smaller and more slender and found only in extreme West Texas.Prairie rattlesnake (Crotalus viridis viridis) is a slender rattler that is greenish or grayish, with rounded blotches down the middle of its back. Average length is about three feet and its found in the grassy plains of the western third of the state
California. It is home to 8 species of venomous snakes, all Rattlesnakes: Southern Pacific Rattlesnake (Crotalus viridis helleri) Great Basin Rattlesnake (Crotalus viridis lutosus) Northern Pacific Rattlesnake (Crotalus viridis oreganus) Western Diamondback Rattlesnake (Crotalus atrox) Red Diamondback (Crotalus ruber) Sidewinder (Crotalus cerastes) Speckled Rattlesnake (Crotalus mitchellii) And last but not least, the Mojave Rattlesnake (Crotalus scutalatus) Florida comes in second with six species of venomous snakes, three Rattlesnakes(Eastern Diamondback, Timber, and Pygmy) and three others(Copperhead, Water Moccasin, and Coral Snake).
The largest known to have been reported was six feet in length. Most "large snakes" are often reported but never confirmed. The Timber rattler is usually an average of three to four feet in length. The Tennessee Outdoorsman (see related link) is reporting a large snake killed recently and is working to confirm its actual size, it may be a new record for the state.
yeah, they are rattlesnakes (western diomond-back, I think) & western black widows The western diamondback is found only east of the Cascades. Black widows, of course, are arachnids (spiders), not reptiles.
Yes, check out the picture here October 4, 2010 Carolina Beach Today: Monster Sized Rattlesnake Found on Topsail Island The pygmy rattlesnake may be found there. The eastern diamondback is found on the NC coastal plain, where it is rare, and restricted to the southeastern corner of the state. The snake mentioned in the above photo was killed in Georgia.
As far as I know, there are two types of rattlesnakes in Colorado on the front range: the western diamondback and the western or prairie rattler. Neither are particularly aggressive (I've stepped on a western diamondback and not been bit) but both are dangerous and should be avoided. I'm not sure what kinds there are in the high country or the western slope. I'm assuming the western diamondback and maybe the timber rattler. The above answer is actually incorrect for the most part. There are no Western Diamondbacks in Colorado and Westerns are one of the most aggressive of the Croatalus. The species in Colorado are the prairie rattlesnake (croatalus veridis veridis), and the faded midget rattlesnake (croatalus concolor). The prairie rattlesnake can be found to elevations above 9000' and pocesses a myotoxic venom with a LD50 (leathal dose 50) value of around 1100 micrograms per kilogram body weight. The LD value is a measure of toxicity where if you lined up 10 mice of the same body mass and injected them with equal vollumes of venom, 50% would die. The faded midget has a highly neurotoxic venom of, if I recall correctly, is around 50 to 100 micrograms per kilogram body weight and is found in the Dinosaur National Park area. A cousin of the rattlesnake is also found in south eastern Colorado, the western massasagua (Sistrusus catanatus edwardsii). I do not recall the LD50 value of it's venom. I'm not questioning either answer above, as I'm not an expert (nor do I really know anything!) however I'm providing a link to the Colorado State University site that says that there are Western Diamondbacks throughout Colorado and the Massasagua in the SE. Again, I don't know, just providing an additional data source from some folks that are indeed experts. Finally, I almost stepped on a rattler today while on a run just outside of Boulder Colorado (Superior). It looked like a Western Diamondback to me.
In Arizona, the most dangerous animal is most likely the western diamondback rattlesnake. This venomous snake is responsible for the majority of snake bites in the state and can be found in various habitats across Arizona, posing a threat to humans who may inadvertently come into contact with them. It's important to be cautious and stay alert when exploring areas where snakes may be present.
The most venomous snake in North Carolina is the Eastern Diamondback Rattlesnake. It is the largest venomous snake in North America and can be found in the southeastern part of the state, particularly in the coastal regions and the sandhills.
There are four types of venomous snakes that live in Iowa. However, you are not likely to encounter any of them. They are the Timber Rattlesnake, Prairie Rattlesnake, Massasauga Rattlesnake and Copperhead.
There are rattlesnakes in Idaho. Both the prairie rattlesnake and the Great Basin rattlesnake are found there. Only the extreme northeast part of the state has no rattlenakes.
Very rare but they do exist, mostly in the southwestern part of the state, but have been seen elsewhere. Don't believe anything the state of Maine says about wildlife, they don't have enough budget to have a clue.
