Antsingy leaf chameleon description

KingdomAnimalia
PhylumChordata
ClassReptilia
OrderSquamata
FamilyChamaeleonidae
GenusBrookesia (1)

The Antsingy leaf chameleon is much smaller than most chameleons, but is the largest of the Brookesia (dwarf) chameleon species. It has a limited ability to change colour and looks like a tiny armoured dragon, with thorny spines running down its back and sides (2). It is dull in colouration, with a dark brown body and a lighter brown head. This suits its lifestyle though, as it hides amongst the dead leaf litter, and is therefore well camouflaged (4).

As a forest floor dwelling chameleon this species does not have a prehensile tail to assist tree climbing. Instead, its tail is short and stumped, and also has spines running down it (5). Its eyes have two rounded crests behind them, and are almost completely covered by brown eyelids, leaving only a narrow opening (5).

Also known as
armoured chameleon, stump tailed chameleon.

Length: up to 11cm (2)

Antsingy leaf chameleon biology

The Antsingy leaf chameleon lives amongst the leaf litter and on low branches on or close to the forest floor where it feeds on small insects such as small flies and termites (4). It stalks prey slowly and, when within range, flicks out its muscular tongue at great speed, catching the prey on the tongue tip and pulling it back into the mouth (6).

In the tropical climate of Madagascar, reproduction occurs mainly during the rainy season (2). The Antsingy leaf chameleon, like most other chameleons, is oviparous (5). Females lay their eggs in soft soil or piles of dead foliage on the forest floor, where natural decomposition of the leaves provides a constant level of heat and humidity (7). Hatching occurs after four to six weeks, and there may be two to five eggs per clutch, with females laying two clutches per year (8).

Antsingy leaf chameleon range

This species is endemic to Madagascar (1), a large island off East Africa’s coast. There it is found in the northern part of the Tsingy de Bemaraha National Park in the Melaky Region (2).

Antsingy leaf chameleon habitat

Like other members of the Brookesia genus, the Antsingy leaf chameleon has specific habitat requirements. It exists in primary or relatively untouched tropical deciduous forests where there is a dense leaf litter. This dense leaf litter is important as it provides food for the Antsingy leaf chameleon. During the night it perches on low twigs, stems and leaves (2).

Antsingy leaf chameleon status

The antsingy leaf chameleon is classified as Endangered (EN) on the IUCN Red List (1), and listed on Appendix I of CITES (1) (3).

IUCN Red List species status – Endangered

Antsingy leaf chameleon threats

Chameleons are favoured as pets across the world due to their fascinating appearance and behaviour. Collection and trade has therefore taken its toll on many chameleon species, but international trade in this species is now prohibited (9). However, habitat degradation remains a threat, even though the species is found within a national park. As this species depends on the presence of leaf litter for food, shelter and laying its eggs, and also on low shrubs and seedlings for roosting at night, its survival is dependent on maintaining the existing vegetation structure within the Tsingy forests (5) (10).

Antsingy leaf chameleon conservation

The Antsingy leaf chameleon is listed on Appendix I of the Convention on International Trade of Endangered Species (CITES), and as such international trade of this species is illegal (3). Its survival is not immediately threatened in the wild, although it is still justifiably a conservation priority because of its limited range and the continued degradation of its favoured habitats within the national park (1) (2) (10).

Glossary

Deciduous
A plant that sheds its leaves at the end of the growing season.
Endemic
A species or taxonomic group that is only found in one particular country or geographic area.
Genus
A category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
Oviparous
A method of reproduction in which eggs are laid and embryos develop outside of the mother’s body.
Prehensile
Capable of grasping.
Primary
Relating to forest, forest that has remained undisturbed for a long time and has reached a mature condition.
