Legless lizard

Legless lizards are a fascinating group of creatures that look similar to snakes but are actually a type of lizard. They have lost their limbs or reduced them to the point where they can't be used for movement. These lizards go by many names, including the family Pygopodidae, and can be found in many parts of the world.

One way to tell legless lizards apart from snakes is by looking for features like eyelids, external ear openings, and a notched tongue instead of a forked one. They also usually have two lungs of roughly equal size and a long tail, unlike snakes.

Many different families of lizards have evolved to lose their limbs. Examples include the Anguinae, which are found in Europe, Asia, North America, and North Africa, and the Pygopodidae, all of which live in Australia except for two species found in New Guinea. These lizards have adapted to life without legs in many interesting ways, making them unique members of the animal world.
