Madame Berthe's Mouse Lemur

While the pygmy marmoset may be the smallest monkey, the title of smallest known primate goes to Madame Berthe’s Mouse Lemur (Microcebus berthae). The seasonal weight is approximately 30 g, and the average body length is 9.2 cm. One of the many species of Malagasy lemurs that have evolved via considerable diversification as a result of unidentified environmental mechanisms and circumstances is Microcebus berthae. In western Madagascar's Kirindy Forest, this primate is primarily found. It was previously believed to be a rediscovery of M. myoxinus after its discovery in the dry deciduous forest of western Madagascar in 1992, but comparative morphometric and genomic research showed that it was actually a distinct species, M. berthae.

The dorsal pelage of the Microcebus berthae is short, thick, and bicolored in cinnamon and yellow ochre. A tawny tint characterizes the middorsal stripe. This species' flanks are a blend of light chamois and light pale neutral gray, while the midventral region is chamois in hue. The underfur on the dorsal and ventral surfaces is a neutral blackish gray tint. Tawny, short hair covers the tail. The ears and crest are tawny in hue as well. A slender dark band encircles the orbits. The space in between the eyes is a warm shade of cinnamon. The feet and hands are a drab brown color.
