While Kentucky is known for its bluegrass, thoroughbred horses, and country music stars, it is also home to dozens of snake species.  Among the 32 snake species found in “The Bluegrass State,” four are venomous.

The Kentucky Department of Fish and Wildlife Resources (KDFWR) compiled a report of all 32 venomous and non-venomous snakes found in Kentucky.  Based on information gathered from the KDFWR’s Kentucky Snakes booklet, here methods of identifying Kentucky’s venomous snakes, as well as profiles of the 4 venomous snakes found in Kentucky.

How to Identify Kentucky’s Venomous Snakes

All of Kentucky’s venomous snakes belong in a group known as “pit vipers.”  In the Kentucky Snakes booklet, the KDFWR provided a couple of tips for distinguishing between Kentucky’s venomous and non-venomous snakes.

• Kentucky’s pit vipers have a sensory “pit” found on the side of the head in between the nostril and eye.
• Venomous snakes have vertically shaped pupils.

In addition, Kentucky’s four venomous snakes all have heads shaped like spades, in which the neck of the snake is not as wide as the back of the head.  However, this is not a definite source of venomous snake identification, in that several species of non-venomous snakes can defensively flatten their heads into a similar triangular shape.

Kentucky’s 4 Venomous Snakes

1. Copperhead (Agkistrodon contortrix)

This snake can be found in every corner of Kentucky.  It is also one of the most commonly misidentified snakes, because of its various shades of coloring that are similar to many of Kentucky’s non-venomous snakes.  The copperhead can be found in lengths ranging from a few inches, to over 3 feet.  They usually feed on small mammals like mice, but have been known to eat lizards, frogs, etc.

While the coloring of a copperhead can vary from a quite literal reddish-copper color, to shades of brown, this snake species is most clearly identified by the distinctly shaped pattern on its body.  The pattern is most commonly described as “hourglass,” in that the bands are wider at the sides and narrower in the middle.

2. Western Cottonmouth (Akistrodon piscivorus leucostoma)

This snake – found in the Western part of the state – is similar in length to the copperhead, although the longest Western cottonmouths can reach nearly 4 feet in length.  It is a nondescript, dark-colored snake which can be difficult to identify on appearance alone.  Young cottonmouths have a body pattern similar to that of a copperhead, but much of this pattern fades with age.

You can typically find these snakes near water.  Western cottonmouths feed on a wide variety of prey including various rodents and even other snakes.  If cottonmouths feel threatened they will bare the inside of their white-colored mouths.  Cottonmouths will also vibrate their tails as a defense mechanism.

3. Timber Rattlesnake (Crotalus horridus)

The timber rattlesnake is the king of the state’s venomous snakes as far as size is concerned.  These monsters can grow up to 5 feet in length, and are heavy-bodied.  Sometimes timber rattlesnakes can be solid black, but they are often yellow, gray, brown, or have a greenish color, with a darker shade of band that crosses the body.

Timber rattlesnakes can be found in the woods of Kentucky in most every area except for parts of Central and Northern Kentucky.  These snakes are not aggressive by nature, and will lie in wait for their next meal to approach, which is most often a squirrel.

4. Western Pygmy Rattlesnake (Sistrurus miliarius steckeri)

This tiny snake – only averaging between 5-20 inches in size – is only found in three specific counties in Kentucky: Calloway, Trigg, and Lyon.  Thus far, the Western pygmy rattlesnake has not been extensively studied in the state of Kentucky, so much of the information gathered by the KDFWR was from pygmy rattlesnake behaviors exhibited in other locations.

Like the cottonmouth, the pygmy rattlesnake is typically found around water.  The pygmy is a lighter grayish-brown color, and has dark-patterned spots on its body.  It may have rusty-colored bars or stripes along its back.  Like other venomous snakes, the pygmy rattlesnake likes to feed on rodents, and even preys on small snakes and frogs.

In a state known for recreation and outdoor activities, it is important to provide education about potentially dangerous wildlife, instead of inciting fear based on exaggerated notions or facts.  Unprovoked attacks from these venomous snakes is highly unlikely.  In fact, only around 10 deaths occur annually in the U.S. from venomous snake bites.

If you see any of these snakes, or think that you have seen one keep your distance, do not try to capture or kill the snake, and contact the Kentucky Department of Fish and Wildlife Resources at 1-800-858-1549 for further information.  In the rare case that you are bitten by a venomous snake, please seek medical attention immediately.

The big four venomous snakes in Asia are the four snakes that are most common to kill. These snakes are all quick to bite and can be deadly in a very short period of time.  What truly makes the big four dangerous, however, is the fact that they are all found in and around the human population.  This leads to more venomous snake bites than in most countries, and in turn, more deaths.

Each of these powerful venomous snakes are capable of killing a human, and each of them can be readily found throughout the cities of India.  These venomous snakes are kind of a win/lose situation for the residents there – on the one hand they keep the vermin population in check, and on the other they are deadly if you are bitten.  Anti-venin is available widely throughout India in the event of a snake bite, and is a must if you are bitten by these big four snakes.

You will notice that the lengendary king cobra is not on this list of the big four.  The reason?  The king cobra is a reclusive snake that is content to hang out in the jungle.  For this reason, they do not come in contact with the people of India nearly as often.  Therefore they are not as dangerous.  A bite from a king cobra is as deadly as they come, but they are just much rarer.

Here are some interesting notes about each of the big four venomous snakes of Asia:

The Indian Cobra – also called a monocled cobra.  The Indian cobra is the cobra of legend that has a pair of monocled glasses on it’s back.  They are quite venomous, and will bite readily if you surprise or harrass them.  This is the snake that is used by snake charmers in India.

The Russell’s Viper – This snake is one of the most feared snakes in Asia.  One reason is because the snake is so tough to see, and so quick to bite.  They will strike without warning, and deliver a highly potent painful deadly snake bite.  The Russell’s viper is no joke in India.

The Saw-Scaled Viper – This little buggar is interesting in that it sounds much like a small rattlesnake.  The sound that it makes comes from rubbing it’s own scales against one another to create a buzzing noise.  This noise is sure to get people’s attention in India as they know the danger of this highly aggressive viper.

The Common Krait – Another potentially deadly snake that is famous in India.  It appears this

snake is prone to climbing into bed with you in pursuit of a rodent or other vermin.  This is not a nightime surprise I would want to experience.  The common Krait is a beautiful but potentially deadly reptile.

Copperhead

Perhaps no other venomous snake in North America is more widely confused than the copperhead.  The copperhead actually has three different subspecies throughout North America.  These subspecies are all quite similar, and all venomous.  The copperhead snake is also the most common snakebite in North America among the dangerous snakes.  This fascinating reptile is not the evil serpent people think.

How Dangerous is The Copperhead

The copperhead has venom that is roughly half the toxicity of a rattlesnake.  Additionally, the copperhead also has relatively small fangs and delivers a much smaller amount of venom.  Because of these factors, the copperhead often is a much less serious snake bite than that of the cottonmouth or rattlesnake.  Still, as with any snake bite, it is considered a medical emergency and can be extremely dangerous.  The copperhead is not a ready biter, but will bite if it feels threatened.  Often, people accidentally step on them due to their fantastic talent of blending with their surroundings.  The vast number of a copperhead bite victims never see the snake.

Where Do You Find The Copperhead

The copperhead is found throughout the United States and is the most widely distributed venomous snake in the country.  They like to hang out in brush, under leaves, and anywhere that they can find a meal.  They are also the most likely venomous snake to encounter around your home.  The copperhead is very adaptive in this way.

What Does The Copperhead Look Like and How Big Do They Get?

A copperhead snake will generally grow to a maximum of about three feet.  They all have copper colored heads, and have a ground color of pink, brown, or even tan depending on the subspecies.  They have triangular shaped heads, and the trademark facial pits that pit vipers are known for.  They also have markings that are smaller around the spine and widen as they go towards the underside of the snake.  These markings are darker than the ground color of the copperhead.

What Does The Copperhead Eat?

The copperhead eats small rodents, vermin and anything else they can capture.  They have been known to kill and eat lizards and other similar types of prey as well.
