Meet the Aussie rat pack representing the Chinese zodiac
According to the more than 2000-year-old Chinese zodiac, 2020 is the Year of the Rat. People born in the Year of the Rat are said to be clever, charming and hard-working. Their namesake animals however are rarely described as such.
The most well-known rat in Australia is the common house (or black) rat. This introduced species of rat is found in urban populations. They spread diseases, pose a threat to native wildlife and keep residents up at night as they scurry in walls and rooves chewing on cables and wires.
Like many introduced animals, rats have native Australian counterparts. They are often indistinguishable to the untrained eye but are much better representatives of the characteristics of the rat zodiac.

The water-rat – the clever; Often referred to by their Indigenous name, rakali, the water-rat is the largest of Australia’s native rodents (40cm – 70cm in length, including their tail).
As one of only two amphibious mammals in the county (the other being the platypus), the water-rats’ body is cleverly designed for its habitat. Found throughout Australia, they live in burrows on the banks of permanent bodies of brackish or fresh water e.g. lakes, dams and urban rivers. They have webbed hind legs, a flattened head, a rudder-like tail, small ears and thick, soft, waterproof fur.
Their waterproof coat almost became their downfall in the 1930s and 1940s. At a time when fur coats and hats were the ‘must-have’ fashion accessory, water-rats were poached for their glossy pelts following a ban on fur imported from the United States. They are now a protected species and their population has recovered to a ‘low priority risk’ conservation status.

The hopping mouse – the charming; Unlike introduced species of rats and mice, hopping mice have inhabited Australia for more than 4 million years.
Only five (of 11) species of hopping mice still exist; the Spinifex Hopping Mouse, the Mitchell's Hopping Mouse, the Northern Hopping Mouse, the Dusky Hopping Mouse and the Fawn Hopping Mouse. The latter three species are classified as ‘vulnerable’ due to habitat degradation (drought and overgrazing) and predators including cats and foxes.
Each species of hopping mouse can be found in a concentrated section of sand plains or dunes across Australia. They live in burrows or in the hummocks of spinifex and cane grass, often close to water. However, this nocturnal mouse can survive in the desert without drinking, accessing all their water from their food which includes seeds, insects, fungi and even small reptiles.
With a tail almost one-and-a-half times the length of its body, round, fur-less ears and large eyes, these mice are at their most charming as they hop across the landscape like miniature kangaroos on their long, hind legs.

The antechinus – the hard-working; At a fleeting glance - which is all this animal is likely to give - the antechinus does bear a striking resemblance to a common mouse/rat. So much so, they are also known as marsupial mice.
But on closer inspection of the 10 species of native antechinus, their longer faces and feet, and large, thin ears distinguish them as unique, Australian marsupials. Their habitats are spread around coastal, country regions where they build nests in trees, vegetation and sometimes peoples’ homes.
Reproduction is a life and death experience for the hard-working antechinus. At 11 months of age, males receive all the sperm their body will ever produce, and they go on a mating spree until they die from a testosterone and stress-induced breakdown of their immune system. Females will mate with different partners, often simultaneously, giving birth to litters with multiple fathers. With no open pouch for their young, newborns attached to a teat and need to hold on to feed and survive while the female scurries through the undergrowth.
All of these clever, charming and hard-working animals can be found in pockets of the Southern Queensland Landscapes region. If you find one injured, please phone WIRES on 1300 094 737.
