Scientists found the world's smallest reptile in Madagascar. It is a chameleon the size of a sunflower seed. They are just 22mm long. At first, the scientists thought the chameleons were babies. They later found they were adults. The scientists called them "nano-chameleons". The scientists tried to find more, but didn't find any.
Madagascar has most of the world's chameleons. The chameleon's survival is in danger because of deforestation. A scientist said the area is now protected, "so [they] will survive". A lot of Madagascar's rainforest could disappear by 2070 because of deforestation. This would put many of the island's unique species in danger.
