## Summary

The gray mouse lemur (Microcebus murinus), grey mouse lemur or lesser mouse lemur is a small lemur, a type of strepsirrhine primate, found only on the island of Madagascar. Weighing 58 to 67 grams (2.0 to 2.4 oz), it is the largest of the mouse lemurs (genus Microcebus), a group that includes the smallest primates in the world.  The species is named for its mouse-like size and coloration and is known locally (in Malagasy) as tsidy, koitsiky, titilivaha, pondiky, and vakiandry.  The gray mouse lemur and all other mouse lemurs are considered cryptic species, as they are nearly indistinguishable from each other by appearance…
