Ctenophorus maculosus
''Ctenophorus maculosus'', commonly known as the Lake Eyre dragon lizard or salt-lake ground-dragon, is a species of agamid lizard endemic to South Australia. ''C. maculosus'' mainly inhabits the edges of salt lakes in South Australia, from which its common names are derived. It survives in this harsh habitat through adaptive mechanisms to tolerate high temperatures and lack of free water. The female ''C. maculosus'' possesses unique male rejection techniques which are currently the focus of further research.
==Description==
''C. maculosus'' can be identified by a white to pale grey dorsal surface with black blotches and a white ventral surface with a dark longitudinal dark streak. Black and brown spots are observed throughout its body. This cryptic coloration allows the species to blend into the salt surface it inhabits, and color variations are found depending on the specific population’s environment. The adult male is about long (including tail), and the adult female is slightly shorter at . ''C. maculosus'' possesses small, sunken eyes protected by serrated eyelids and eye linings. Its nostrils are connected to its nasal cavity by only a narrow downward slit. This nasal structure is adaptive for preventing nasal blockage from burrowing in sand. Other sand-burrowing American lizards have also developed similar nasal structures via convergent evolution, including species in the genera ''Uracentron'', ''Holbrookia'', and ''Phrynosoma''.〔〔
