Brookesia nana

Brookesia nana, also known as the nano-chameleon, is a species of chameleon endemic to montane rainforests in northern Madagascar (North of 16°S). Unlike some chameleons, Brookesia nana does not change colors, which is an example of paedomorphism. The majority of northern Brookesia species are restricted to rainforest.

The species was discovered by herpetologist Frank Glaw and other German researchers in 2021 in the rainforest on the Sorata massif in northern Madagascar. Described in 2021, it could represent the world's smallest reptile. 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. Miniaturism is believed to evolve from habitat loss.
