Description: With a maximum total length (including tail) of 27 inches, F. oustaleti is considered the largest species of chameleon, but that claim is occasionally contested by the Parsons chameleon Calumma parsonii, as the Parsons tends to be more heavily built but slightly shorter in length. The head bears a high casque with several crests, and a dorsal crest consisting of 45 or more small triangular spines, runs along the spine. The colouring is quite variable, usually being largely grey or brown, with females often being more colourful than males. There is a line of large scales and may be a row of four large circles running along the flanks.

Habitat: It is found in a number of different habitat types including dry deciduous forest, humid evergreen forest and montane savanna, including degraded forests, land cleared for agriculture and even urban settings. It is seldom found deep in the forest interior, but more on the edges.

Range: This species is endemic to Madagascar where it occurs throughout most of the island, across an elevational range from sea-level to 1,300 m altitude. It has been introduced into Florida.

Found in these States: FL

Diet: The diet of F. oustaleti includes invertebrates such as large insects as well as some vertebrates such as small birds and reptiles. This is also one of several chameleon species that are known to consume fruit.

Reproduction: After mating, the female lays up to 60 eggs after a gestation period of around 40 days.

Status: Listed as Least Concern as the species is widespread across Madagascar, and relatively common even in disturbed habitats. Taxonomic research may require a re-evaluation of this species, and if it is found to be considerably less widespread and more ecologically specialized than is currently recognized it will require reassessment.
