Examples of Geckos: Gekkonidae

Geckos are a family of lizards known as Gekkonidae, characterized by their sticky toe pads for climbing smooth surfaces and nocturnal habits. They possess large eyes, excellent night vision, and communicate using unique vocalizations, unlike most other lizards. Geckos are found worldwide, except for Antarctica, and are popular in the pet trade due to their vibrant colors and patterns.

Examples of Iguanas: Iguanidae

Iguanas belong to the family Iguanidae and are typically larger than other lizards, with robust bodies and spiky Crests along their backs. They are mainly herbivorous and prefer warm, tropical environments. Iguanas are known for their strong territorial behavior, especially the males, and are common in the pet trade. They have unique adaptations, such as the ability to process toxic plants and a well-developed dewlap for communication.

Examples of Chameleons: Chamaeleonidae

Chameleons, part of the family Chamaeleonidae, are known for their remarkable ability to change color, which they use for communication and camouflage. They have unique zygodactylous feet, separately mobile eyes for panoramic vision, and long, sticky tongues for catching insects. Chameleons thrive in wooded and arboreal habitats, primarily in Madagascar and Africa, and are admired for their cooperative hunting and insectivorous diets.
