The Arnhem Land rock rat (Zyzomys maini) also known as the Arnhem Rock-rat[1] and by the Indigenous Australian name of Kodjperr[2] is a species of rodent in the family Muridae. It is found only in Australia.
The rat typically grows to a size of 15 centimetres (6 in) in length with a mass of 100 to 150 grams (4 to 5 oz). It can be distinguished from other local rodents by its long whiskers, swollen tail and Roman nose.[2]
It is an entirely terrestrial and nocturnal species, with a diet that consists mainly of seeds, fruit and some other vegetable matter. The rat will cache large seeds or at least move them to sites where it is safe to eat.[3] It is able to breed all year round but females are rarely found to be pregnant late in the dry season.[4]
Endemic to the sandstone massif of western Arnhem Land, the population is highly fragmented as a result of the topographic complexity of the deeply dissected plateau. The preferred vegetation for the rat is monsoonal rainforest which is found patched throughout the landscape.The total area of occupancy is estimated to be from 100 to 1,000 square kilometres (39 to 386 sq mi).[2]
The species is listed as near threatened with the IUCN, although the population of the species is in decline. Approximately 30% of the population is found within Kakadu National Park.[1]
