Before, the dwarf gecko was known to be the smallest known reptile ever to be discovered, but in recent years, several dwarf chameleons from Madagascar have been constantly contending for the title. Its scientific name is Brookesia nana. The lizard was discovered in Madagascar by the Bavarian State Collection of Zoology. On average, the males are measured to be as little as 13.5 mm and females are around 29 mm. It is hardly any bigger than a key on keyboard, earning itself the nickname of nano-chameleon.
