Hey there! Today, we’re diving into the world of venomous snakes. These fascinating creatures can be found almost everywhere on Earth, except for Antarctica. There are over 3,000 different types of snakes, and scientists are still discovering new ones!
Snakes are reptiles with long, thin bodies and no legs. While most snakes are harmless, some are venomous and can be dangerous. Venomous snakes have special teeth called fangs that are connected to venom glands. When they bite, they inject venom into their prey.
Snakes live in many different places, from forests and deserts to woodlands and oceans. The Amazon rainforest is home to a large number of snake species. Snakes are cold-blooded, which means their body temperature changes with their surroundings. They love warm places where they can soak up the sun’s heat. However, some snakes live in colder areas and slow down during winter in a state called brumation, similar to hibernation.
Snakes are carnivores, meaning they eat other animals. Smaller snakes might eat rodents, birds, and insects, while larger snakes can eat bigger animals like deer or even crocodiles! Some snakes have special diets, like the egg-eating snake that loves to munch on eggs.
Snakes have a unique way of eating. They can stretch their mouths wide open to swallow their prey whole. They don’t chew their food, so it can take a long time to digest a meal. Their teeth are curved and can move back into their mouths, which helps them swallow without getting stuck.
Did you know that snakes don’t have taste buds like we do? Instead, they have a special organ called Jacobson’s organ that helps them “taste” the air. When a snake flicks its tongue, it picks up scents and brings them back to its mouth to detect what’s around.
All snakes can swim, moving in a way that looks like the letter “S.” Some snakes, like sea snakes, spend most of their lives in water and can hold their breath for up to an hour!
Snakes play a crucial role in the environment by controlling pest populations. They help keep the number of rodents, like mice, in check, which is great for farmers. Some snakes even eat other snakes, like the king snake that preys on rattlesnakes.
Unfortunately, many snake species are in danger because of habitat loss and other threats. It’s important to respect snakes and their role in nature.
If you ever see a snake, it’s best to leave it alone. Snakes usually avoid humans and only bite if they feel threatened. Remember, even non-venomous snakes can bite if they feel scared.
We hope you enjoyed learning about venomous snakes! If you’re curious about other amazing animals, check out more resources at learn.org. Happy exploring!
Snake Habitat Exploration: Take a walk in your local park or garden with an adult and observe the different environments you see. Can you find places where a snake might like to live? Look for warm, sunny spots, or areas with lots of plants. Draw a picture of a perfect snake habitat based on what you learned from your walk.
Venomous vs. Non-Venomous Snakes: Create a simple chart with two columns labeled “Venomous” and “Non-Venomous.” Use books or the internet with an adult’s help to find pictures of different snakes. Cut out or draw these pictures and place them in the correct column. Discuss with a friend or family member what makes a snake venomous and how you can tell the difference.
Snake Diet Detective: Pretend you are a detective trying to solve the mystery of what different snakes eat. Choose a snake from the article and research its diet. Then, create a “menu” for that snake with pictures or drawings of its favorite foods. Share your menu with the class and see if they can guess which snake it belongs to!

Hi everyone! Today’s video is all about venomous snakes. If you want to read along, you can download this lesson plan from our website, learn.org. Ready? Let’s get started!
What are venomous snakes? Everywhere in the world, except Antarctica, you can find snakes. There are over 3,000 types of snakes, and scientists are still discovering new ones. Snakes are reptiles that have long, thin bodies but no legs. While most snakes are harmless, some are venomous and quite dangerous. Snake habitats range from forests to deserts, woodlands to oceans, but the most significant number of snakes can be found in rainforests, most specifically the Amazon rainforest.
Snakes are cold-blooded, so their body temperature varies with their environment. They love to live in tropical regions because they can use the sun’s warmth to maintain their body temperature. However, not all snakes live in warm areas; some live in colder climates and stay warm by reducing their activity during the winter months. During winter, snakes hide away in holes or dens, but they do not hibernate. Instead, they enter a state of rest called brumation. Before brumation occurs, they must eat more than usual to survive the winter, similar to bears. During brumation, snakes remain still and slow down their metabolism, which is how they convert food into energy. Some species, like timber rattlesnakes, will share a den and huddle together for warmth, sometimes with as many as 100 snakes in one den.
There are around 700 different species of venomous snakes, and about 250 species are capable of killing a human with one bite. Venomous snakes have two grooved or hollow, needle-pointed teeth called fangs. These fangs connect to glands that hold the venom. When a snake bites, the muscles contract and release the venom through ducts in their fangs, injecting it into their prey.
What do they eat? Snakes are carnivores, meaning they only eat other animals. The type of animals they eat depends on the size of the snake. Smaller snakes eat rodents, birds, and insects, while larger snakes may eat deer, pigs, and alligators or crocodiles. Some snakes have specialized diets that have adapted to specific types of food. For example, the egg-eating snake primarily eats eggs.
Additionally, snakes have a unique way of eating; they have stretchy ligaments that allow them to open their mouths wide enough to swallow their prey whole. They never chew their food, and it can take a snake anywhere from a couple of days to weeks to finish a meal. Snakes’ teeth are curved and can be pulled back into their mouths, preventing them from getting caught while unhinging their jaws. The larger the snake, the longer the teeth, which helps them puncture heavier animal hides or pierce through the feathers of their prey.
Other interesting facts: Snakes do not have taste buds on their tongues like humans do. Instead, they have a taste sensor on the roof of their mouths. When a snake flicks out its tongue, it picks up scents in the air, and when the tongue comes back into its mouth, the sensor picks up those scents. These taste sensors are known as Jacobson’s organs, allowing snakes to “taste” the air around them to find prey or avoid predators.
Every snake species can swim, moving in a manner similar to the letter “S.” However, some snakes prefer water more than others. For instance, sea snakes spend most of their lives in the water and can remain submerged for up to an hour. Snake venom contains neurotoxins that attack the nervous system. The most common way to treat a venomous snakebite is with antivenom, which is an antibody that can disable a particular venom’s toxins if injected quickly after a bite. In that case, the antibodies can neutralize the poison, potentially saving a person’s life or limb. Each antivenom must be made for a specific type of venom; the first one ever made was in 1895 to combat cobra venom.
Why are snakes important to the environment? Snakes are beneficial because they provide natural pest control. Without predators, mice would reproduce too quickly, which would be detrimental to farmers and their crops. Snakes offer an environmentally friendly way to control rodent populations. Some snakes even eat other snakes; for example, the king snake preys on rattlesnakes because it is immune to their venom.
Unfortunately, snakes are under serious threat due to habitat destruction, urban development, disease, and human actions. As a result, many snake species are endangered, and some are on the brink of extinction. While you may not love snakes, we must respect their right to coexist on the planet with us, as they play an essential role in maintaining biodiversity.
Generally speaking, if you encounter a snake, it’s best to avoid it. Snakes usually try to avoid humans and only become aggressive if they feel threatened. Therefore, never attempt to pick up or capture a snake; even a non-venomous snake can deliver a painful bite when it feels threatened.
We have learned many interesting facts about venomous snakes. Let’s see what you remember!
How do venomous snakes inject venom? When a snake bites, the muscles contract and release the venom through the ducts in their fangs.
