Description
[edit]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.[5] The body of the lizard is depressed with proportionately large forelimbs.[6]
Habitat And Distribution
[edit]The physical and behavioral traits of the Ctenophorus species vary depending on their respective habitats within Australia.[7] 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.[8]
All specimens are found located either within or at close proximity to rocky areas.[8]
Behavior And Diet
[edit]Members of the C. Decresii Species group portray sexually dimorphic dorsal coloration.[9] 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.[10]
They feed on ants in arid zones.[11] Ants constitute of majority of the diet by percentage, while grasshoppers, termites, hermipterans, scorpions, spiders, beetles, and wasps are eaten in a smaller amount.[12]
Common Predators of the Ctenophorus are Brown falcons, Australian Kestrels, Bustards, Large snakes and the monitor lizards.[13]
