Multimammate mouse
Introduction: For the technically minded, scientists have decided that the main difference between the multimammate mouse (Mastomys coucha) and the Natal multimammate mouse is the former has a 2n chromosome number (36 chromosomes per nucleus as opposed to 32); the two thus meriting separate status. Most of the data concerning this mouse is applicable to the Natal species.
Distribution: Isolated populations in Namibia, centring around the Khomas Hochland region.
Diet: Grasses and seeds such as Acacia seeds, dry pods, pulpy bits of wild fruits and insects. As with the Natal species, it will revert to cannibalism in periods of food shortage associated with high populations.
Colouring: Long, soft buffy-grey fur with white to dark-grey underparts. The short tail is brown above and white below.
Breeding: 12 pairs of mammae. Litters average 10 to 16. Females breed throughout the year. Gestation period is 23 days.
Size: Adult males reach a total head body length of 145mm. Tail 156mm.
