Ctenophorus fordi, commonly known as the Mallee dragon, Mallee military dragon,[3] or Mallee sand-dragon,[2] is a species of agamid lizard occurring in the arid parts of southern Australia.[3][1]

Description

Adult Mallee dragons range in colour from yellow-brown to reddish-brown, with a pale midlateral stripe, head and body flecked with dark brown or black, and a white underside. The throat of males is marked with black spots or bars, which often connect to form a 'V' shape. Adults have a total length (including tail) of 16.5–19 cm (6.5–7.5 in).[4][5][6] Their lifespan is short, only around 12–18 months.[6]

Distribution

Mallee dragons are found throughout the arid to semi-arid parts of south-eastern Western Australia, across central South Australia to north-western Victoria, into north-western and central-western New South Wales, as well as into a small portion of south-western Queensland.[4][5][7][6]

Ecology and behaviour

The Mallee dragon lives in sandy arid to semi-arid areas of Mallee woodland and spinifex, as well as vegetated sand dunes.[7][8] They prefer areas of Mallee that haven't been burnt for around 30 years, when spinifex cover is at its maximum.[9] Emerging from dormancy in August, males appear about four weeks earlier than females.[6] Active even on very hot days, they forage in sandy, open areas, and will dash for cover into nearby grasses or low bushes if disturbed or pursued.[5][7][6] Males are territorial.[6]

Diet

One of only a few Australian lizard species specialized in eating ants, their limited diet consists primarily of ants.[4][10]

Reproduction

Mating occurs in spring. Multiple clutches of 2–3 eggs are deposited up to three times a season, with eggs hatching after 50–70 days.[6]

Conservation actions

Although considered to be of 'Least Concern' by the IUCN, the Mallee Dragon occurs in several protected areas, including the Mallee Cliffs National Park[11] and Yathong Nature Reserve in New South Wales, the Currawinya National Park in Queensland, and the Murray-Sunset National Park in Victoria.[1]
