You may mistake a slithering snake for a legless lizard, because they look just alike. If the "snake" moves with only a side-to-side motion, it may be a legless lizard. Take this quiz to see whether you can tell them apart.
Legless lizards evolved from legged lizards.
They look very much alike as they slither along the ground.
They both have forked tongues, scaly exteriors and other snakelike characteristics.
You may find a slithering legless lizard in every continent except Antarctica.
Legless lizards eat mice, bird eggs, beetles, grasshoppers, snails and spiders.
The legless lizard is also known as the glass lizard.
Unlike snakes, glass lizards have inflexible jaws, and cannot open wide enough to swallow a whole animal that is bigger than its head.
Snakes have no eyelids, and the glass lizard has moveable eyelids.
Most of the lizard's length is in its tail, which it can drop off when threatened by predators.
The legless lizard may regenerate one additional tail in its lifetime.
The tail may take anywhere from several months to two years to grow back.
The legless lizard uses it sides to move, and is limited to side-to-side motion.
Snakes move using their sides and belly scales, and have a greater range of motion than the legless lizard.
