Brookesia nana, also known as the nano-chameleon, is a species of chameleon endemic to montane rainforests in northern Madagascar.[2] Described in 2021, it could represent the world's smallest reptile.[1] Unlike some chameleons, Brookesia nana does not change colors.

The species was discovered by herpetologist Frank Glaw and other German researchers in 2021[1] in the rainforest on the Sorata massif in northern Madagascar. Brookesia nana is not arboreal, as it tends to inhabit the forest floor. It is likely that the species is endangered due to deforestation in Madagascar.[3] Miniaturism is believed to evolve from habitat loss. [4]

Description

The nano-chameleon is blotchy brown in color. Adult males measure 22 mm (0.87 inch) in total length (including tail), while females are slightly larger at 29 mm (1.1 inches).[1][5] Like other Brookesia species, females are generally larger than the males. The reasons for its diminutive size are currently unknown, as many vertebrates grow as they mature.[3]
