The Malagasy giant chameleon (Furcifer oustaleti), also known commonly as Oustalet's chameleon, is a large species of chameleon which is native throughout Madagascar, but has also been introduced near Nairobi in Kenya (though its current status there is unclear) and in Miami-Dade County in the United States. It occurs in a wide range of habitats, even among degraded vegetation within villages, but is relatively rare in the interior of primary forest. Wikipedia →
