Chameleon: Example of Lacertile Reptile

What they are - biological definition

Lacertils are scaled reptiles (order Squamata), which belong to the suborder Sauria. They are mainly found in Asia, Africa and America. There are about 300 known species of lacertils.

Summary of main features:

- They live mainly in woodland and forest regions. However, species can be found in desert regions.

- They are reptiles of small and medium size (between 10 and 45 cm in length).

- They have long tails and slender bodies.

- Have colors that vary from species to species.

- Lacerticles feed mainly on insects. Some species eat seeds. While other large species (eg komodo dragon) eat eggs and meat from dead animals.

- They have large scales on the head and small and granular scales on the back.

- There is sexual dimorphism in most species. That is, there are males and females with different physical characteristics.

Examples of tearing:

- Chameleons

- Lizards

- Geckos

- Glass snake (which is actually an apoda lizard)

- Iguana

- Gila monster (lizard)

- Komodo Dragon (lizard)

Biological Curiosities:

- The only poisonous lacertyl species is the gila monster (Heloderma suspectum). This dangerous lizard is found in northwestern Mexico and the southwest of the United States.

- Geckos and some species of lizards have an interesting resource for getting rid of predators. The tail is detached from the body, remaining in motion for some time. While the predator is distracted by the tail, the reptile may flee. After some time the tail of these lacertiles grows again (regeneration).
