Madame Berthe's mouse lemur on a branch in Madagascan forest at night

Madame Berthe's mouse lemur

The minute Madame Berthe's mouse lemur is believed to be the world's smallest living primate, at less than 100mm long and weighing only 30g. These tiny lemurs were only recently described as a species, in 2000. They are nimble and move quickly through the trees of Madagascar's dry forests in search of food, from fruit and the favoured honeydew of plant hopper larvae to chameleons. Madame Berthe's mouse lemurs have the unusual ability to lower their metabolic rate and body temperature during the cool, dry winter months which saves valuable water and energy.

Tropical dry forest Tropical dry forest
Tropical dry forests, in contrast to rainforest, have to survive a long dry season each year, so the predominantly deciduous trees shed their leaves to cope with it. Sunlight can then reach the ground, so the season that's bad for the trees is good for the forest floor.
