The Veiled Chameleon (Chamaeleo calyptratus) is a tree-dwelling lizard native to the Arabian Peninsula, specifically Yemen and Saudi Arabia. It is named for the distinctive casque, or helmet-like structure, on top of its head, which is more pronounced in males and can grow up to 8 cm (3 inches) tall. Veiled chameleons are known for their vibrant colors, which can range from green to yellow, blue, and orange, and their ability to change hues based on mood, temperature, and environment.
They grow to about 45-60 cm (18-24 inches) in length, with males typically being larger. Veiled chameleons are insectivores but also eat vegetation, especially in the wild. Like other chameleons, they have zygodactylous feet for gripping branches, independently moving eyes for 360-degree vision, and long, sticky tongues to catch prey. They are popular pets due to their unique appearance and behaviors, but they require careful husbandry and controlled environments to thrive.
