The Arnhem Land rock rat (Zyzomys maini) is a special type of rodent that lives only in a small part of Australia. People also call it the Arnhem rock-rat or by its Indigenous Australian name, kodjperr. It's part of the Muridae family, which includes many kinds of mice and rats. You can find this unique rat only in the Top End region of the Northern Territory.

About Its Name
Scientists give every animal a special name. The Arnhem Land rock rat was first described by a scientist named Darrell Kitchener in 1989. He was studying the group of rats called Zyzomys.
The name maini was chosen to honor Bert Main. He was a zoologist from the University of Western Australia who was retiring.
What It Looks Like and Does
This rat usually grows to about 15 centimetres (6 in) long. It weighs between 100 to 150 grams (4 to 5 oz), which is about as much as a small apple.
You can tell it apart from other local rodents by a few things. It has long whiskers and a tail that looks a bit swollen. It also has a unique nose shape, sometimes called a "Roman nose."
Daily Life
The Arnhem Land rock rat lives only on the ground. It is a nocturnal animal, meaning it is active mostly at night. During the day, it rests and hides.
Its diet mainly consists of seeds and fruits. It also eats other plant matter. These rats are smart about food. They will often hide large seeds in safe spots to eat later.
They can have babies all year round. However, it's rare to find pregnant females late in the dry season.
Where It Lives
The Arnhem Land rock rat is found only in the sandstone areas of western Arnhem Land. This region is in the Northern Territory of Australia.
The land there is very rocky and uneven. This means the rat's population is spread out in small, separate groups. It prefers to live in patches of monsoonal rainforest. These small forest areas are scattered throughout the rocky landscape. Scientists estimate that the total area where these rats live is about 100 to 1,000 square kilometres (39 to 386 sq mi).
Protecting the Arnhem Land Rock Rat
The IUCN lists the Arnhem Land rock rat as "near threatened." This means its population is declining, and it could become endangered if we don't protect it.
About 30% of these rats live inside Kakadu National Park. This national park helps protect their habitat and gives them a safe place to live.
