The Malagasy giant chameleon or Oustalet's chameleon (Furcifer oustaleti) is a large species of chameleon which is native to entire Madagascar, but also has 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. They’re endemic to Madagascar and is found throughout the island. It inhabits a very wide range of habitat types 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, but more on the edges. With a maximum total length (including tail) of 68.5 cm (27 in), F. oustaleti (Malagasy giant chameleon or Oustalet's chameleon) 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. The colouring of F. oustaleti is quite variable. Males are usually largely grey or brownish, sometimes with reddish-orange feet or underparts. Females are more variable and often more colourful than males, with base colour or markings in red, yellow and green being possible, and the eyelids can sometimes be blue.
