These chameleons were native to East Africa, but in recent years have been introduced into California, Hawaii, and even Florida. Young Jackson's chameleons are brownish in color, developing brighter green coloration at about 4 or 5 months of age. Lifespan: Five to 10 years in captivity. Size: Jackson's chameleons range in size from about 9 to 13 inches in length (including the tail). Males tend to be larger than females. Behavior and Temperament Jackson's chameleons are territorial and should be housed individually. Handling is stressful to them, so as with other chameleons, they are pets better suited to being watched than handled. Housing Chameleons should never be kept in a glass terrarium. They need the ventilation provided by a mesh enclosure; fine metal or fiberglass mesh is not recommended. Vertical space is essential since chameleons like to climb high up off the ground. An outdoor cage can be used when the weather is warm enough, as long as overheating is prevented.
