| status2 ref = They are part of the primate order, and classified in the family Cheirogaleidae. Previously, both populations of giant mouse lemurs were believed to belong to one species. The northern giant mouse lemurs are small nocturnal lemurs endemic to Madagascar. They weigh about , and have long, bushy tails and relatively small ears. Their large testicles are an indication of their promiscuous copulation system. These lemurs have been found to use communal sleeping nests including multiple males, which is an uncommon behaviour in lemurs.

The word zaza means child in Malagasy. The name was chosen because the northern giant mouse lemur is the smaller of the two giant mouse lemur species, and because of a wish to emphasize the responsibility of the current generation of Malagasy children for the conservation of Malagasy animals for future generations. The habitat is split by two rivers, the Mahavavy River to the north and the Maevarano River to the south. In some areas it is further separated by the Sambirano River. Home ranges cover 0.52– 2.34 ha. An estimated 385–1,086 individuals per km2 are present throughout the region. The northern mouse lemur is nocturnal, feeding predominantly during the second half of the night. On average, individuals stay approximately up in the canopy. During the day they sleep in group exclusive tree holes. Nesting groups are 2–8 individuals in size, made up of both sexes and any age class, and include unrelated males. The species is listed in CITES Appendix I.
