2. Rat Snake
   Reticulated Python

Reticulated pythons come from Asia and can routinely reach lengths of 19 feet, with at least one exceeding 22 feet. Though they are not poisonous, they are constrictors. Thanks to their size, they are capable of killing (and in some cases, eating) human beings.

1. Hill Keelback
   Mojave Rattlesnake
2. Gaboon Viper
   Corn Snake

Corn snakes are sadly often mistaken for copperheads in the wild and meet a tragic end as a result. The difference is that corn snakes are quite docile and not venomous. Their ability to control the pest population makes them quite beneficial.

1. Sri Lankan Pit Viper

   Black Mamba
2. Mexican Racer
   Tentacled Snake

The black mamba is one of the deadliest snakes in the world, and not just due to its highly potent venom. The mamba is also incredibly fast and will frequently strike when provoked (and sometimes when not provoked at all).

1. Western Hognose Snake
   Indian Krait
2. Lancehead

1. Zebra Spitting Cobra
   Arizona Coral Snake
2. Milk Snake
   Blind Snake

The bold red, black and yellow color patterns of the coral snake make them very easy to pick out of a crowd, though you might want to avoid them. They're venomous and they also engage in something called "cloacal popping" which is a very polite way to say they fart when threatened.

1. Collett's Snake
   Blood Python
2. American Copperhead
   Palm Viper

American copperheads are pit vipers that can be found all over the United States. They aren't typically aggressive. However, because they tend to freeze when startled rather than fleeing, many bites will occur simply due to people not noticing them.

   Red-Backed Rat Snake
2. Indian Python
   Eastern Diamondback Rattlesnake

Eastern diamondback rattlesnakes are considered the most venomous snakes in North America. They are the largest rattler species but, despite all of that, they're not known for being overly aggressive. Of course, if you hear the warning rattle, it's a good indication that you should back off.

1. Pipe Snake
   Black-Headed Python
2. Texas Night Snake
   Blind Snake

Black-headed pythons live in dry, desert areas and are non-venomous. When they're backed into a corner, they're surprisingly chill as far as snakes go and will often strike with a closed mouth.

1. King Cobra
   Lancehead
2. Spotted Python
   Timber Rattlesnake

The king cobra is fairly easy to recognize thanks to its massive size and distinctive hood. The hood flares up when the snake is threatened, but its the length, up to 13 feet, and in at least one case over 19 feet, that is most dramatic.

1. Gold-Ringed Cat Snake
   Burrowing Cobra
2. Indigo Snake
   River Jack

The gold-ringed cat snake is mildly venomous and quite easily recognizable thanks to its namesake bands of golden yellow scales. Even though the venom of the snake is mild, they also get a little jittery when people try to handle them, so bites are not uncommon and result in painful swelling.

1. Sidewinder
   Scarlet Snake
2. Cat Snake
   Banded Krait

Sidewinders are rattlesnakes but don't have venom quite as potent as other rattlesnakes. That isn't to say a sidewinder bite is a walk in the park. It can cause severe pain, swelling, nausea, dizziness, chills and more.

1. Patchnose Snake
   Snail-Eating Snake
2. Water Moccasin
   Milk Snake

Milk snakes got their name from a myth about their behavior. People used to believe milk snakes would sneak up to cows and suck the milk from their udders. A snake doesn't have the ability to do that, mind you, so it's not true at all.

1. Red-Necked Keelback
   Tokara Habu
2. Sunbeam Snake
   Tentacled Snake

The red-necked keelback can envenomate when it bites, but it doesn't do so in a way common to snakes. Rather than inject venom with fangs, venom mixes with their saliva and will simply ooze into bite wounds.

1. Gaboon Viper
   Paradise Flying Snake
2. Grey Rattler
   Desert Cobra

Gaboon vipers not only have the longest fangs of any snake species, but they also have the highest venom yield of any snake as well. That said, gaboons are not known to be particularly aggressive, so bites are not all that common.

1. Ball Python
   Coral Snake
2. Grass Snake
   King Snake

Ball pythons are the smallest pythons and tend to be extremely docile, which is why they make such good pets. The name "ball" python comes from the snake's tendency to curl up in a ball when they're frightened.

1. Sand Adder

1. Stilleto Snake
   Gopher Snake
2. Olive Sea Snake

1. African Rock Python
   Brown Tree Snake
2. Gray Ratsnake
   Small-Eyed Snake

Gray ratsnakes have a number of clever defense mechanisms. They can play dead, freezing their bodies in crooked poses, as well as rattle their tail against surfaces to make a warning buzz. And most effective may be the way they release a bit of nasty smelling goo from their back end.

1. Ribbon Snake
   Shield-Tailed Snake
2. Monocled Cobra

1. Bird Snake
   Boa Constrictor
2. Copperhead
   Blue Krait

2. White Taipan
   California Kingsnake

California kingsnakes make for great pets as they are typically not very aggressive, and they aren't venomous. If provoked, they will bite, though it's not generally a painful affair. They're also highly resistant to the venom of other snakes, which allows them to attack and eat things like rattlesnakes.

1. Brown Tree Snake

2. River Jack
   Dwarf Pipe Snake

1. Tree Boa
   Sharp's Anaconda
2. Green Mamba
   Asian Vine Snake

1. Kukri Snake
   Mussurana
2. Krait
   Boomslang

1. Eastern Racer
   Black Snake
2. Beauty Rat Snake
   Glossy Snake

Eastern racers are fairly accurately named snakes. They're found east of the Rocky Mountains, and they're also quite fast when they're in danger, which is where the racer part of the name comes from. If you do catch one, they may not be venomous, but they do bite.

1. Eastern Rattler
   Red Racer

1. Rat Snake
   Death Adder
2. Gopher Snake
   Twig Snake

Death adders didn't get their name for no reason. They're some of the most venomous snakes on Earth. Oddly enough, the name of this snake in Australia was originally "deaf" adder because the snakes stand their ground and refuse to flee when approached, which made some think they couldn't hear.
