The casque starts as a tiny swelling on a hatchling and grows to two inches tall, and mature males have a larger casque and body. Nose to tail-tip, adults reach 12 to 18 inches long. Chameleons can grow up to 100 times heavier within a year of hatching. One study filmed 12 veiled chameleons of different sizes, from about 1 gram to 200 grams. A veiled chameleon can live four to eight years. Its native home is southwestern Saudi Arabia and Yemen, where it lives on high, dry plateaus and in forests and river valleys. These are mountain regions with very little water. It prefers to live high up in trees or lower down in bushes and shrubs. > **A Head That Catches Its Own Water** At night, droplets of moisture roll down the casque and into the chameleon's open mouth. ## A Spring-Loaded Tongue Chameleons do not fire their tongues with muscle power alone. They stretch elastic tissue and use its recoil, which releases energy more rapidly than muscles contracting directly could. A 2016 study that filmed 20 chameleon species measured the veiled chameleon's tongue accelerating at up to 514 meters per second squared, more than 50 times the pull of gravity, and reaching full length in as little as 26 milliseconds. In chameleons, the tip of the tongue is a ball of muscle that rapidly forms a small suction cup as it hits its prey. Once the prey sticks, the chameleon draws it back into its mouth. ## Eyes on Two Targets at Once Like other chameleons, it can rotate and focus each eye separately to look at two different things at the same time, giving it a full 360-degree view around its body. When it sees prey, both eyes can focus in the same direction for a clearer view. ## Shy, but Aggressive to Its Own Kind A veiled chameleon eats mainly insects, but it is one of the few chameleons that also eats plants, taking leaves and flowers. It adapted to eating leaves as a source of water in the dry seasons. Veiled chameleons are shy by nature: when startled or threatened, one may curl up tightly, darken in color, and play dead. Toward each other they are very aggressive, and they prefer to live alone. Males are very territorial. Males and females only tolerate each other when ready to breed. The IUCN lists the species as Least Concern. Carried abroad by the pet trade, it is known to live in isolated populations in southern Florida and on the Hawaiian island of Maui. ## Frequently Asked Questions ### How fast does a veiled chameleon's tongue move when it strikes? A 2016 study that filmed 20 chameleon species measured the veiled chameleon's tongue accelerating at up to 514 meters per second squared, more than 50 times the pull of gravity, and reaching full length in as little as 26 milliseconds. Chameleons do not fire their tongues with muscle power alone. They stretch elastic tissue and use its recoil, which releases energy more rapidly than muscles contracting directly could. *(Source: [Anderson 2016]())* ### Why does a veiled chameleon have a tall crest on its head? That tall crest, called a casque, acts like a water collector. Veiled chameleons live in the mountain regions of Yemen and Saudi Arabia, where there is very little water, and at night, droplets of moisture roll down the casque and into the chameleon's open mouth. *(Source: [San Diego Zoo Wildlife Alliance]())* ### How do a veiled chameleon's eyes work when it's hunting? Like other chameleons, it can rotate and focus each eye separately to look at two different things at the same time, giving it a full 360-degree view around its body. When it sees prey, both eyes can focus in the same direction for a clearer view. *(Source: [San Diego Zoo Wildlife Alliance]())* ## Sources 1. [Chamaeleo calyptratus (veiled chameleon).
