Top facts

Brookesia confidens has not yet been classified by the IUCN, but all Brookesia species are listed on Appendix II of CITES (2) (3).

Leaf chameleons of the Brookesia genus are renowned for their tiny size (4), and Brookesia confidens is no exception. First discovered in 2007, and formally described in 2012, this species was one of four tiny leaf chameleons to be newly discovered in northern Madagascar (1).

Although some variation in Brookesia confidens has been described, this species is generally light grey or pale beige on the head, back and tail, and brown on the sides. The limbs are almost entirely dark brown, and along the back pointed tubercles form a complete line. Brookesia species are characterised by a short, non-prehensile tail (1).

Under stress, Brookesia confidens is able to rapidly change colour, revealing a pale stripe down the centre of its back which is conspicuous against its darker sides. Some individuals are known to display dark brown spots on the flanks, a pattern also believed to be related to stress (1). 

Brookesia confidens is known only from Ankarana National Park, Antsiranana Province, in northern Madagascar (1).

Within Ankarana National Park, Brookesia confidens is restricted to a single area of dry deciduous forest with underlying eroded limestone and rocky outcrops (1).

The restricted locality of Brookesia confidens suggests that this species has a preference for very specific habitat types, particularly as no specimens have been found in similar areas nearby (1).

Brookesia confidens is active on the ground during the daytime, foraging in the leaf litter, and at night climbs into the vegetation to rest on small branches, 5 to 20 centimetres from the ground (1). There is no data currently available on the diet of Brookesia confidens.

Like other members of the Brookesia genus, Brookesia confidens may be representing a case of island dwarfism, a phenomenon whereby a species adapts over time to being restricted to a particular habitat, for example an island, by becoming smaller (5).

Due to its restricted range, Brookesia confidens may be particularly vulnerable to disturbance of its habitat (5). However, the future looks hopeful for this endemic species, as its range is located within a well-protected nature reserve, Ankarana. Additional protection is provided by the limestone formations surrounding the reserve, making the area fairly inaccessible (1).

Brookesia species, in general, are often threatened by habitat loss and collection for trade (3).

Although no conservation measures are currently in place for Brookesia confidens, it is hoped that this species will remain well protected within the Ankarana National Park (1).

All Brookesia species are listed on Appendix II, and one species on Appendix I, of the Convention on International Trade in Endangered Species (CITES), meaning that any international trade of these species should be carefully controlled and monitored (2) (3).
