Snake Facts

What is the first thing you think of when you think of a

snake? Why?

This is information on snakes that shows how

interesting and cool they really are.

A. Snakes are reptiles with no legs. They move by using their muscles to push their scales against the ground or other objects.

B. They are also exothermic.

  1. This means they depend on the temperature of their surrounding environment to regulate their body temperature.
  2. If it is cool they use the sun or a warm rock or even pavement to warm them up.
  3. If they get too hot - they have to cool down - so they will move into the shade.
  4. This is called thermoregulation

C. When the weather begins to cool, snakes will go into hibernation.

  1. When it gets too cold snakes cannot move fast enough to catch or digest their prey.
  2. This is actually a semi-hibernation state when the snake sleeps most of the time and doesn’t eat very much.
  3. When the weather warms up they begin to wake up. They may come out of semi-hibernation several times in the winter as it warms and cools.

D. Some snakes lay eggs.

  1. Snake eggs are soft and leathery not like hard easily breakable chicken eggs.

E. Some have live babies.

  1. Some snakes take care of their offspring for a week or so.
  2. Other snakes have the offspring and leave.
  3. The young (or juveniles ) begin to take care of themselves very soon after they are born.

F. Some snakes are venomous.

1. Venom is a toxin secreted by some animals and is transmitted in some way stun or kill prey or to an enemy for protection. 2. There are other venomous animals such as scorpions and bees.

  1. Most snakes are not venomous, but do not touch a snake without an adult present!

G. Snakes shed their skin as they grow.

  1. But they can feel your vibrations when you are walking or stomping.

M. All snakes have teeth.

  1. Some snakes have small teeth and some have bigger teeth.
  2. Some even have long teeth at the front of their mouth called fangs.
  3. Different teeth are used for different reasons.
  4. Snakes with fangs use those fangs to inject venom into their prey.
  5. The venom usually kills the prey. It is also used in defense against predators.

N. If a snake feels threatened it may bite even if it is not a venomous snake. Other things snakes do when they are threatened are: roll over and play dead, puff up to look bigger, try to get away, strike, vibrate their tail (sounds like a rattle snake), hiss, defecate or musk (make a stinky smell).

O. Snakes are important because they eat mice, rats and bugs. They also eat frogs, lizards, birds, bird eggs and rabbits. Some snakes like the kingsnake, even eat other snakes including rattlesnakes.
