Description
Jonah's mouse lemur has small ears and the characteristic huge eyes of lemurs with a distinct white stripe between the eyes. It has short, dense fur with a white with slightly yellowish belly and a brownish back. It weighs and has a body length of around and its tail measures around 13 cm as well.
Distribution
Jonah's mouse lemur lives in northeastern
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, f ...

Conservation status
The forested area in the region where the Jonah's mouse lemur is found is undergoing massive
deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. Ab ...
