Lizard

Lizard is a general term for reptiles belonging to the order Lacertilia. Lizards are vertebrates with skin covered in small scales, and typically have four legs, a tail, and open eyes. They are found on all continents except Antarctica, particularly in warm and temperate regions.

Lizards belong to the order Squamata, which also includes snakes. For this reason, lizards and snakes share many characteristics, such as skin shedding and the structure of the jaw bones. Lizard species number in the tens of thousands and vary greatly in size, ranging from tiny species a few centimeters long to large species such as the Komodo dragon.

Body Structure

The lizard's body consists of a head, torso, abdomen, and a long tail. The scales on the skin prevent water loss, helping the animal survive in arid environments. Lizards are ectothermic animals: their body temperature is regulated by basking in the sun or seeking shelter. Many species can shed their tail when caught, and later regenerate a new one (autotomy).

Behavior and Diet

Most lizards feed on insects, worms, spiders, and other small animals. Some species eat plants and fruits, while larger species may prey on larger animals or livestock. They rely on keen vision and quick movement; some use their tail as a weapon to strike at predators.

Reproduction

Most lizard species lay eggs, which are buried in soil or under rocks. Some species bear live young. In some species, the temperature of the place where the egg is laid determines the sex of the offspring. Parents typically do not care for their young after hatching.

Relationship with Humans

Lizards are found in homes, gardens, and farms. Some people regard them favorably because they eat insects. In many parts of Somalia, lizards are considered harmless animals. However, some species are threatened by habitat loss and the wildlife trade.
