Snake vs Lizard for Kids
Snakes and lizards are close reptile relatives in the order Squamata, but their bodies usually reveal different designs. Snakes have long limbless bodies, fixed clear eye coverings, and no external ear openings. Most lizards have four legs, movable eyelids, and visible ear openings, although legless lizards prove that legs alone are not a perfect clue.
Snake
- Type: Reptile
- Group: Squamate
- Known for: Limbless bodies, flexible jaws, forked tongues, and slithering movement
- Diet: Carnivore
- Special skill: Moving without legs and swallowing prey with a highly flexible skull
Lizard
- Type: Reptile
- Group: Squamate
- Known for: Scaly bodies, movable eyelids, external ear openings, legs in most species, and tail tricks
- Diet: Omnivore
- Special skill: Running, climbing, burrowing, and dropping the tail in many species to escape predators
Quick Answer
Quick answer: Snakes have long limbless bodies, no movable eyelids, and no external ear openings. Most lizards have legs, can blink, and have visible ear openings. However, some lizards are legless, so the eyes, ears, jaw shape, and body proportions provide better clues than legs alone.

How Are Snakes and Lizards Alike?
- Both snakes and lizards are reptiles in the order Squamata.
- Both have scales, lungs, backbones, and body temperatures influenced by their surroundings.
- Both use their tongues and scent-sensing organs to gather information.
- Both may lay eggs, although some species give birth to live young.
- Both shed their outer skin as they grow.
How Are Snakes and Lizards Different?
- Snakes have no functional walking legs, while most lizards have four legs.
- Snakes cannot blink because their eyes are covered by clear spectacles, while most lizards have movable eyelids.
- Snakes have no external ear openings, while most lizards have visible ear openings.
- Snake jaws and skull bones are especially flexible for swallowing prey, while lizard skulls are generally less flexible.
- Many lizards can release part of the tail to escape danger, while snakes do not use this common lizard escape trick.
Snake vs Lizard Showdown
Reptile showdown: The snake wins for maximum length and prey-handling strength, while the lizard takes the land-speed round because many species sprint on powerful legs. Stealth, social life, and swimming are ties because both groups contain specialized champions. The lizard wins our weirdest-fact pick because many species can detach a wriggling tail and later regrow part of it.
Fun Snake vs Lizard Facts
They Belong to the Same Reptile Order
Snakes and lizards both belong to Squamata, the largest living reptile order. Snakes evolved from lizard-like ancestors, so they are deeply nested within the wider squamate family tree.
Legs Are Not a Perfect Clue
Most lizards have four legs and snakes have none, but several lizard groups evolved long limbless bodies. A legless lizard can often be identified by movable eyelids, external ear openings, and a long detachable tail.
Blinking Eyes vs Clear Spectacles
A snake’s eye is covered by a transparent scale called a spectacle, so the snake cannot blink or close its eyes. Most lizards have movable eyelids, although a few lizards also have clear eye coverings.
Hidden Hearing vs Visible Ear Openings
Snakes have inner ears but no external ear openings. They are especially sensitive to vibrations traveling through the ground, while most lizards also have visible openings that carry airborne sound toward the eardrum.
Many Lizards Can Drop Their Tails
When grabbed by a predator, many lizards can detach part of the tail. The wriggling tail distracts the attacker while the lizard escapes, and a replacement may grow later, though it is usually not identical to the original.

Snake vs Lizard FAQ
What is the easiest way to tell a snake from a lizard?
Check several features together. Snakes lack movable eyelids and external ear openings, while most lizards can blink and have visible ear openings. Legs alone can mislead because some lizards are legless.
Is a snake a type of lizard?
Snakes and lizards are both squamates, and snakes evolved within the wider lizard-like branch of the reptile family tree. In everyday language, however, snake and lizard describe different body forms.
Do snakes unhinge their jaws?
No. A snake does not dislocate its jaws. Flexible skull bones, stretchy ligaments, and independently moving lower-jaw sections let its mouth open around large prey.
Can every lizard regrow its tail?
No. Tail dropping and regrowth occur in many lizards, but not in every species. The replacement tail may also differ from the original.
Can snakes and lizards hear?
Yes. Both have inner ears. Snakes lack external ear openings and detect ground vibrations especially well, while most lizards can also receive airborne sound through visible ear openings.

Snake and Lizard Detective Activity
Snake and Lizard Detective Activity
Draw a snake on one side with a clear eye spectacle, forked tongue, no external ear opening, and a long limbless body. Draw a lizard on the other side with legs, blinking eyelids, an ear opening, and a detachable tail. Add a small legless lizard in the middle and circle the clues that prove it is not a snake.
