The short-eared rock-wallaby (Petrogale brachyotis) is a species of rock-wallaby found in northern Australia, in the northernmost parts of Northern Territory and Western Australia. It is much larger than its two closest relatives, the nabarlek (Petrogale concinna) and the monjon (Petrogale burbidgei).[3]
Taxonomy
The species was described by John Gould in 1841,
In 2014 a genetic and morphological study identified a separate species, the Eastern short-eared rock-wallaby (Petrogale wilkinsi), previously thought to be P. brachyotis. It occurs in the Kakadu and Litchfield National Parks, weighs less, and has stronger markings and colouring.[4]
A number of subspecies have been recognised, but these may be invalid.[1]
Description
A species of Petrogale, known as rock wallabies, that is varies in its size and coloration. The grey-brown coloration of the fur is interspersed with silver hair that highlights the overall coloration. the underside is pale grey. The length of the head and body combined is from 415 to 550 millimetres, and they weight 2.2 to 5.5 kilograms. The tail is relatively short for the genus, 320 to 550 mm, a dark brown to blackish tuft of fur appears at the terminus and the colour is otherwise cinnamon brown. The ears are also relatively small, less than half the length of the head, measuring for 40 to 48 mm. The cinnamon colour also appears at the legs, broken by a buff or whitish stripe at the thigh that extends over the flank and over the shoulder, where a darker patch appears below the forelimb. A buff patch at the side of the snout has an off-white coloured stripe below that reaches to the eye. A dark stripe beginning at the crown of the head continues to the middle of the back. All the coloration is duller and the striping less distinct in populations found at the Victoria River and Kimberley region.[5]
Behaviour
The short-eared rock-wallaby is a gregarious vegetarian, found in rocky hills and gorges. It is variable in its appearance but is generally grey-brown with white areas around its face and legs. It is not considered threatened.[3]
Distribution and habitat
Petrogale brachyotis has a patchy occurrence within a wide distribution range, extending west from the border of Queensland and the northern territory through the Top End to the Windjana Gorge in the northwest of Australia.
In Aboriginal language and culture
Speakers of Kunwinjku in West Arnhem Land call the wallaby badbong, and people would traditionally travel with spears into the escarpment to hunt them.[6]
Conservation
The IUCN Red List notes the conservation status of the species was assessed as least concern in 2016.
