Berthe's mouse lemur is the smallest primate animal on the planet. Its body length is about 9 centimeters, and its weight is only 30 grams.
Berthe's mouse lemur differs from other lemurs by having the smallest size in the world. It is important for the forests of Madagascar because it disperses plant seeds and serves as part of the food chain.
