About Snakes
   
  A Common Garter Snake
 

Common Garter Snake

   
 

   

Snakes are elongate legless carnivorous reptiles of the order Serpentes. Found all over the world, except in the arctic, they play an important role in both the ecosystems and cultures of every region they occupy.

Snakes evolved from Lizards, and share many traits with them. Snakes and lizards are cold-blooded and have scaly skin, flattened diamond-shape heads, beady eyes, long sensory tongues, and a taste for live prey. While some lizards are content with a vegetarian snack, all 2,900+ species of snakes found throughout the world are carnivorous. The snake's ability to creep silently while climbing trees, squeezing through blades of grass, or burrowing in dirt or sand make it an excellent hunter and ambush predator. They have evolved a lightening-fast strike and fangs designed to lock prey into their jaws. Some snakes take on prey that they can easily handle: smaller rodents, birds, eggs--nothing difficult. Others go for larger prey, a meal that will last a while. A snake can devour prey much larger than its head or body may seem to be able to handle. Their highly mobile jaw bones can unlock, twist and turn to open wide and manipulate their meals. Snakes can devour meals that will take weeks to digest.

Although they all have the slender legless bodies, their colors and sizes can vary greatly. Juvenile snakes can be tiny--fitting comfortably coiled on a quarter, or they can be larger than humans, like the notorious Anaconda. Although most snakes have earthy skin colors, many have taken on bright and bold patterns. Many mimic other, more dangerous snakes as a method of defense. A few species look and behave just like a tree branch in order to hide from predators and prey. Despite their diverse appearance, snakes can be very difficult to identify properly. Like humans with skin and hair color, snakes of the same species can have skin of varying colors, stripes and spots. It'll usually take closer examination to differentiate some common species. Unfortunately most people aren't willing to get in for a closer look.

The majority of snakes spend their time on the ground, in grass, rocks, dirt and sand, but there are plenty of arboreal (tree-dwelling) snakes too. Aquatic snakes, commonly referred to as "serpents," spend a lot of their time hunting in the water, but can also traverse land if need be. Many terrestrial snakes can swim and often do so to hunt or evade predators.

Snakes play an important role in pest control. Their hearty appetite and natural talent for capturing small animals helps keep rodent populations down. In urban areas, snakes can help keep rat populations under control.

 
Snakes in New York
While we have only 16 native snake species in New York State, the pet trade throws a wrench or two into indentifying them. Exotic snakes sometimes make their way from the home terrarium into the wild. The poisonous Coral Snake looks very similar to our native and harmless Milk Snake. Boa Constrictors of all sorts, a very popular group of snake pet, are not native to our area, yet seem to find their way into our lawns and sheds every once in a while. Although finding an escaped exotic snake in the wild is rare, it is something one must keep in mind when identifying a snake.

In New York, common Garter Snakes will account for the majority of encounters. These harmless snakes, tend to vary in color and color markings, but are easy to identify if one gets used to seeing them. Because of their loss of habitat, many snakes take up residence in  our yards, sheds and homes. Some just die out. We have two endangered species of Snake in New York: Eastern Massasauga Rattlesnake and the Queen Snake, and are only found in small isolated populations. The Timber Rattlesnake, more common, but with populations dwindling, is considered a threatened species.

 

 
Poisonous snakes
We have many biting snakes in New York, and some that, while venomous, have little effect on the human body. There are three poisonous snakes here that pose a danger to humans. Luckily they are rare, timid around humans, and strike only when provoked. Snake bites, even from non-venomous species, can pose a health threat if not treated properly. Infection and parasites can result from a snakebite. All snakes, even the small ones, should be handled with caution.

If you are bitten by a snake:

  • Do what you can to get out of there or prevent a second strike.
  • Take note of the snake's size, color, patterns, distinguishing marks. Look for the pupils. Vertical pupils usually mean a venomous snake.
  • Remove constricting items (rings, jewelry, watches). Do not apply a tourniquet to any limbs.
  • Use the limb as little as possible.
  • Snake venom acts quickly. Stop what you are doing and pay attention to your body and how it is reacting.
  • Do not attempt to "suck out the poison."
  • At any indication that the snake was venomous, call EMS (911), or get someone to take you to a doctor or hospital.
  • No one should take any medical advice from non-trained personnel. There is a lot of false information out there.
  • If no immediate medical attention is needed (the snake is not venomous), clean the wound, apply a topical antibiotic and dress if needed. A tetanus booster is highly recommended.
  • See a doctor if you are unsure. It is better to be safe than sorry.

We ask that you do not kill or harm a snake because you think it is poisonous. Identify it first. Snake repellent can help keep snakes off your property.
