Ethiopia and Somalia, to more typically the drier, highland forests and woodlands of Somalia, Ethiopia, Sudan, Tanzania, Uganda, and Kenya. Fossil remains have been found as far north as Israel, however. They are often found in rocky areas or in hollow tree trunks and holes

The maned rat's body can grow up to 14 inches (360 mm) long, or 21 inches (530 mm) from head to tail. The coat consists of long, silver and black-tipped guard hairs over a dense, woolly, grey and white undercoat, with the face and limbs having short, black fur. A mane of longer, coarser

When the animal is threatened or excited, the mane erects and this strip parts, exposing the glandular area. The hairs in this area are, at the tips, like ordinary hair, but are otherwise spongy, fibrous, and absorbent with a honeycomb structure. The rat is known to deliberately smear these hairs
365:
The maned rat was believed to be solitary, but is now known to be somewhat sociable, with multiple animals trapped in the same territory; they purr and groom one another. Thus it is possible they form family groups of a male, female, and offspring. The litter size is 1–3. The young are slightly
269:. This mane is bordered by a broad, white-bordered strip of hairs covering an area of glandular skin. The forelimbs and hind limbs have short black fur. The forefeet are large and digit 1 of the forefeet does not have a claw while digits 2-5 have a well developed claw.
305:. The dorsal surface of the skull is covered with small bony projections which gives it a pebbled look. The projections are 0.3mm across and are separated every 0.3mm. On these grounds, it has been made the type of a family; its dentition, however, is typical

haired at birth and white markings and black stripes on the body are visible after 9 days. By day 13, the eyes open. The hair is sufficiently long that the crest can be erectile by day 20. The newborns become mobile by day 23 and are weaned by day 40.
