It is shy, and not aggressive. It lives in holes and burrows in the ground, to keep out of the severe heat. Therefore, it rarely comes in contact with humans.

Does a Lizard Shed its Skin?

Most people know that a snake sheds its skin, but does a lizard shed its skin?

A lizard is a reptile. Reptiles include snakes, lizards, crocodiles, alligators, caimans, turtles, tortoises, and terrapins. Reptiles lay soft-shelled eggs on land.

The Balkan Slow Worm (Pseudopus apodus) is also a reptile. It is not a worm and it is not a snake. It is a legless lizard. It actually has small (almost invisible), undeveloped rear legs, but it does not use its legs for locomotion. It is not a snake because it has eyelids (snakes do not have eyelids). It has a long tail. It is also known as the Pallas’s Glass Lizard, the European Glass Lizard, the Sheltopusik, or the Giant Russian Legless Lizard.

How do snakes move?

How do snakes move?

Snakes do not have legs, so they slither and slide. But what does this mean?

Snake locomotion (movement) can be serpentine, concertina, rectilinear, or sidewinding.

Serpentine movement is also called lateral undulation, and it is the most common way for snakes to move. The movement looks like an ‘S’ shape. Terrestrial snakes, that live on the ground, use this type of movement. Aquatic snakes, that live in water, also use this type of movement.
