It is important to know how to recognize snakes. If you do get bitten, you will be able to give the necessary information at the hospital so that they can administer the right anti-venom. Today I will show you X of the most common poisonous snakes in the US and tell you all you need to know about them. Take note, many hospitals will administer no antivenin until you have shown all the symptoms of a specific US venomous snake. It make little difference to them how well you can tell one from another. I assume this is an insurance liability thing. If you can somehow without further endangering yourself, and have already called for assistance and or have people with you capable of getting you to medical attention asap, I would seriously consider killing the snake dead dead dead, and taking the damn thing with you so they will administer antivenin ASAP. 1. Coral Snake Looks: You can spot the quite easy because of their alternating, red, yellow, and black bands in this order. Remember it well because there are other snakes that have the same colors, but different patterns. Those snakes aren't poisonous, but take my advice: stay clear of any snake, just to be on the safe side. Coral snakes are shorter than other venomous snakes. They average about 40 inches and have smaller mouths and fangs. Habitat: They are usually found in dry areas with lots of shrub in southern and eastern U.S. Most of the time they stay hidden underground or under leaf litter. You'll see them more active after it rains or in the breeding season. Note that there's an aquatic species, so be careful where you go to cool off in the summer. Temper: Unless threatened, they won't bite or act aggressive. But if they do decide to bite, they hold on and won't let go. This is due to the fact that their venom takes longer to deliver. 2. The Diamondback Rattlesnake Looks: Different species of rattlesnakes have different colorings, but they all have 2 things in common: the diamond pattern and the rattle. Diamondbacks grow to about 3.5-5.5 ft. long. The ones found on the eastern part of the US grow even bigger, reaching 7 ft. Habitat: You'll find them on the southern border of the United States from Florida to Baja California. You'll often find them basking in the sun's rays on a rock, so admire them from a far and move on without disturbing them. The eastern species have been known to climb and are excellent swimmers, so be careful. Temper: They'll often stand their ground and can strike repeatedly from a distance up to 2/3 of their body size. The attacks are lightning fast so stay as far away as possible from them. Diamondbacks have one of the deadliest venoms and people have died within hours of being bitten. 3. The Mojave Rattlesnake Looks: It's similar to the diamondback, only the overall coloration is green-greyish and it grows to 3.4-5 ft. long. Habitat: As you might've guessed from its name, you can run across it primarily in the Mojave Desert. That's why be extra careful when you go to the Grand Canyon. They are common in wide expanses of desert and can often be found near scrub brush. They hibernate during the winter. Temper: They are quite aggressive, especially towards humans. 4. Cottonmouth Snakes Looks: They have a brown, gray, tan, yellowish olive or blackish coloring segmented by dark crossbands. While normally they are about 2 ft. long, some have been known to grow to nearly 6 ft. Their name comes from the white interior of their mouths, which can be seen if the snake feels threatened. Habitat: This is an aquatic snake found in the south and southeast part of the United States. Everything from make creeks, streams, marshes, and lakes are home to the cottonmouth. They're active both in the day time and night time and if it's too hot, you might run into them in the shade. Temper: You know the saying: all bark and no bite? This applies to the cottonmouth. They often engage in a showy threat display without attacking by shaking their tail and letting a musky secretion rip from their anal glands. This doesn't mean that it won't bite if you push it into a corner. As with any poisonous snake, leave it alone. 5. Copperhead Snakes Looks: Copperhead snakes are identified by their coppery colored head and neck. Adults reach lengths of 2 to 4 feet. Habitat: They can be found near water in the forests and woodlands of eastern US. Temper: If they feel directly threatened (you try to touch or pick them up) they will bite. Most venomous snakes flee when people are around, but the copperhead does the exact opposite. It freezes in place, which leads to humans stepping on it. Their bite isn't lethal if treated properly, but it is extremely painful. There are of course many other venomous snakes all around the world, but knowing where to look and how to spot the ones that are around our country, may safe your or a loved one's life one day. As I stated before, and I cannot stress this enough: If you come across ANY type of snake, go the other way. It's safer and wiser. . One last thing I would like to add to this plagiarized article; Their are many color variations I am aware of that are not represented with the two different pics of rattle snakes here. Anyone who can add to that please post and Identify additional US rattlesnakes and the area where the pic is taken.
