What you’ll learn

How Snakes Move Without LegsUnderstand the four ways snakes move and how muscles and belly scales let them travel without legs.Snakes move using strong muscles and wide belly scales called scutes that grip the ground. They have four different ways of moving: the wavy S-shape, sidewinding across sand, a slow straight-line crawl, and the concertina scrunch for climbing. Each method suits a different place, from grass to desert to tree branches.
Super SensesLearn how snakes smell with their tongues, sense heat with pits, and feel vibrations to understand the world.Snakes have incredible senses. Their forked tongues pick up smells from the air, and some snakes have heat pits that let them sense warm animals in the dark. Without outside ears, snakes feel vibrations through the ground with their jaws. Together, these senses help snakes hunt and stay safe.
Constrictors and VenomUnderstand that most snakes are harmless, and learn how constrictors and venomous snakes catch food.Most snakes are harmless and shy. Snakes catch food in two ways: constrictors like pythons squeeze their prey and swallow it whole, while venomous snakes like cobras use fangs to inject a special liquid. Neither way is meant for people, and snakes prefer to avoid us and be left alone.
Record-Breaking SnakesDiscover the biggest, longest, and tiniest snakes, including the anaconda, king cobra, and threadsnake.Snakes come in amazing sizes. The green anaconda is the heaviest, the reticulated python is the longest, and the king cobra is the longest venomous snake and can rear up to eye level. The tiny Barbados threadsnake is small enough to curl up on a coin.
Why Snakes MatterUnderstand why snakes are important to nature, how to stay safe around them, and why they are amazing not scary.Snakes are important because they eat rodents that spread germs and damage crops, and they are food for bigger animals in the food chain. To stay safe, never touch a snake and give it space to slither away. Learning about snakes helps us protect them and see how amazing they truly are.

Questions this course answers

How do snakes push themselves forward without legs?

Snakes squeeze their muscles and use wide belly scales called scutes to grip the ground and slide forward.

Which way of moving do desert snakes use to cross hot sand?

Desert snakes use sidewinding, throwing their bodies sideways to zip across hot, loose sand.

Why does a snake flick its tongue?

A snake's forked tongue picks up scent bits from the air, then presses them against a special spot in its mouth to smell them.

What do heat pits help some snakes do?

Heat pits let snakes like pit vipers and pythons feel the warmth of other animals, helping them hunt even in total darkness.

Are most snakes dangerous to people?

Most snakes are harmless and would rather slither away than bother a person. Only a small number are dangerous.

How does a constrictor snake catch its food?

Constrictors like pythons and boas wrap around their prey and squeeze firmly, then swallow their meal whole since they cannot chew.
