choristoderan

Choristoderans are a group of lizards belonging to the infraorder Choristodera. They are characterized by their unique body structure, which includes a long, slender body, a long tail, and a distinctive head shape. Choristoderans are found primarily in South America, with a few species occurring in Central America and the Caribbean.

The infraorder Choristodera is divided into two families: Cordylidae and Gerrhosauridae. Cordylids are the most diverse group, with over 100 species, while Gerrhosaurids are less diverse, with only about 20 species. Both families are known for their ability to change color, a trait that is particularly well-developed in the Cordylidae.

Choristoderans are primarily terrestrial, although some species are semi-arboreal. They are omnivorous, feeding on a variety of insects, small vertebrates, and plant material. Many species are also known for their ability to regenerate lost body parts, a trait that is particularly well-developed in the Cordylidae.

Choristoderans play an important role in their ecosystems, serving as both predators and prey. They are also of interest to scientists studying evolution, as their unique body structure and regenerative abilities provide insights into the evolution of reptiles.
