Description

C. tjantjalka or Ochre Dragon is characterized as a robust, moderate-sized lizard which differs from other Ctenophorus species on the basis of having the smallest snout length (73mm), lack of banding on tail, and presence of vertebral keel.[2] The body of the lizard is depressed with proportionately large forelimbs.[3]

Habitat And Distribution

The physical and behavioral traits of the Ctenophorus species vary depending on their respective habitats within Australia.[4] This lizard inhabits the interior regions of South Australia, widespread between the Idulkana Range and Oodnadatta in the North, and Coober Pedy and Davenport Range in the South.[5]

All specimens are found located either within or at close proximity to rocky areas.

Behavior And Diet

Members of the C. Decresii Species group portray sexually dimorphic dorsal coloration.[6] Male C. Tjantjalka are uniform light blue with salmon flanks and lack the dark lateral bands on the tail, while females have presence of pale spots.[7]

They feed on ants in arid zones.[8] Ants constitute of majority of the diet by percentage, while grasshoppers, termites, hermipterans, scorpions, spiders, beetles, and wasps are eaten in a smaller amount.[9]

Common Predators of the Ctenophorus are Brown falcons, Australian Kestrels, Bustards, Large snakes and the monitor lizards.[10]
