Malagasy giant chameleon


The Malagasy giant chameleon or Oustalets's chameleon is a large species of chameleon which is endemic to Madagascar, but also has been introduced near Nairobi in Kenya.

Habitat

F. oustaleti occurs in a wide range of habitats, even among degraded vegetation within villages, but is relatively rare in primary forest.

Description

With a maximum total length of, 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.

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. F. oustaleti is known to regularly consume the fruit of Grangeria porosa, Chassalia princei, and Malleastrum gracile, and will do so even during the wet season, suggesting that fruit is not consumed just to obtain water.
Typically, prey is acquired with a long, muscular tongue, while fruit is seized directly with the jaws, but occasional exceptions to this rule have been recorded. In one unusual case however, this species was recorded grasping fruit bearing twigs with the zygodactyl feet and bringing them closer for consumption. Amongst reptiles, this level of food manipulation with the forelimbs is otherwise only documented in some species of monitors lizards and Chamaeleo namaquensis. The latter is also known to feed on plants.

Etymology

The generic name, Furcifer, is derived from the Latin root furci meaning "forked" and refers to the shape of the animal's feet.
The specific name, oustaleti, is a Latinized form of the last name of French biologist Jean-Frédéric Émile Oustalet, in whose honor the species is named.
