About the Oustalet's Giant Chameleon

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.

Furcifer oustaleti is endemic to Madagascar and is found throughout the island. It inhabits a very wide range of habitats including dry deciduous forest, humid evergreen forest, montane savanna, degraded forests, agricultural areas and even urban settings. It is seldom found deep in the forest interior, preferring the forest edges instead.

With a maximum total length (tail included) of 68.5 cm (27 in), Furcifer oustaleti is generally considered the world's largest species of chameleon by this measurement. Exceptionally large Calumma parsonii (Parson's chameleon) and Trioceros melleri (Meller's chameleon) have been claimed to reach even greater lengths, but this remains unverified. F. oustaleti...
