In this article, you'll find all sorts of details related to the existence of these animals, from habitat and behavior to other contenders for the title of the world's smallest lizard.

Which is the Smallest Lizard in the World?

The world's smallest lizard is called Brookesia nana or the nano-chameleon. It is endemic to the rainforests of the northern part of Madagascar and was officially recognized as the world’s smallest lizard in 2021. 

The male grows up to only 13.5 mm long from the snout to the vent, being so tiny that it can easily fit on a person's finger. One distinctive feature is that females grow a bit bigger, measuring around 19 mm. This phenomenon is typical for most chameleons and is referred to as sexual dimorphism. 

Even though the lizard in question has broken the size record, it remains a complete reptile with a gripping tail and an extensible tongue to capture prey.

Where does the World’s Smallest Lizard Live? 

The world’s smallest lizard species, called nano-chameleon  (Brookesia nana), can be found in the tropical rainforests of Madagascar. It is worth noting that these smallest lizards live in the northern part of the country in an area called the Sorata Massif.

These reptiles have adapted to life on the ground, living among the dried foliage and plants. This allows them to remain inconspicuous and safe from predators due to their diminutive size. Humidity and dense trees provide the ideal setting in which these animals can survive, with abundant insects to eat.

What is the Size of the World’s Smallest Lizard?

Brookesia nana, the world’s smallest lizard, is extremely diminutive and fits perfectly on the end of one’s finger. 

The male reaches a total body length of just 13.5 millimeters (0.53 inches), while the female ranges between 19 and 29 millimeters (0.75 and 1.14 inches) long.

Compared to other seeds and insects, the world’s smallest lizard is significantly shorter, and hence it is among the smallest reptiles ever found. Being small makes the creature invisible in leaf litter and helps it evade potential threats in the wild environment.
