How would you get around with no legs? How would you eat with no arms?

  • Have you ever seen a snake?
  • Where did you see it?

Share your story with your parent or teacher.


All snakes are reptiles. This means they have many things in common with turtles, alligators, crocodiles, and lizards. Snakes are cold-blooded.

  • Do you know what it means to be cold-blooded?

Share your answer with your parent or teacher.

Cold-blooded animals need to regulate their body temperature. This means when a snake is too cold, it will lay in the sun to warm up, and when it's too hot, it will hide in the shade to cool down. When a snake is too cold, its body slows down.

  • Have you ever been really cold?
  • What did you do to warm up?

Check out the snake below. This snake is enjoying hot sand in the hot sun! If you have ever owned a pet snake, you know snakes need a heat lamp to keep warm. You will often see snakes enjoying hot rocks that have been heated up by the sun. This is a great way for them to warm up!


 

Snakes are vertebrates. This means they have a backbone. Check out the skeleton above.

  • What do you notice about the skeleton?
  • Can you find the backbone of the snake?

Discuss your answers with your parent or teacher. As you can see, a snake has a very long backbone that extends all the way through its body.

Tell your parent or teacher what it means to be a vertebrate.


 

All reptiles have hard scales on their skin.

  • Can you see the scales on the snake above?

Their hard scales give them extra protection, allow them to retain moisture, help them move, and help them blend into their surroundings.


Snakes come in many different colors.

  • Can you think of some snakes you have seen?
  • What colors were they?

Many snakes come in various shades of green, gray, brown, and black. This helps them blend into their surroundings.

Some snakes have interesting patterns.

  • Did you know certain patterns on a snake can indicate whether or not a snake is venomous (poisonous)?

There are around 2,900 species of snakes on Earth, and only 375 of these snake species are venomous. Some areas have more venomous snakes than others. Here are some ways you can tell if a snake is venomous:

  1. Venomous snakes are usually wide and fat.
  2. If a snake has a rattle on the end of its tail, it is a venomous rattlesnake.
  3. Elliptical eyes (cat eyes) can indicate whether a snake is venomous.
  4. "Red on yellow, you're a dead fellow," is a great way to remember a venomous snake pattern!

There are many types of venomous snakes on earth. If you ever come in contact with a snake in the wild, leave it be! Do not try to catch snakes or kill them. It is not always easy to tell whether or not a snake is venomous. Some snakes may look venomous even though they are completely harmless.

Look at the two snakes below.

  • Can you tell which one is venomous and which one is not?

Share your answer with your parent or teacher.

  • They look very similar, don't they?

The one on the left is a milk snake. Milk snakes are not venomous. The snake on the right is a coral snake. Coral snakes are dangerous to humans because they are venomous. It is easy to confuse one snake for another. Always remember, if you see a snake, leave it alone!

Snakes help humans in many ways. Without snakes, we would have too many insects, mice, rats, and other small animals. Snakes help control the populations of these critters.

  • How do you think they control the population of insects, mice, and rats?

Discuss your answer with your parent or teacher.

That's right! They control the population of these animals by feeding on them! Snakes are carnivores. They eat meat! Unlike most animals, snakes do not chew their food. They open their jaws really wide and swallow their prey whole.

Before moving on to the Got It? section, tell your parent or teacher three interesting facts you learned about snakes. After discussing what you have learned about snakes, move on to the Got It? section.
