Diplodactylus ciliaris
The northern spiny-tailed gecko, scientifically known as *Strophurus ciliaris*, is a species of lizard endemic to Australia. It is characterized by spines above its eyes, resembling eyelashes, and along its tail. This species inhabits arid, semi-arid, and subtropical shrublands, often found in spinifex clumps.

About Diplodactylus ciliaris
Northern Spiny-Tailed Gecko (Strophurus ciliaris)
The northern spiny-tailed gecko, scientifically classified as Strophurus ciliaris, is a species of lizard that is native to Australia. Its common name is derived from the distinctive spines located above its eyes, which give it an 'eyelashed' appearance, and the presence of spines along its tail.
Description and Habitat
This gecko exhibits significant variability in its coloration, ranging from a plain grey to a rich brown with intricate mottled patterns of grey, white, and orange scales. The average adult length is approximately 89 mm (3.5 inches), with females generally being larger than males. Strophurus ciliaris is an arboreal species, meaning it lives in trees and shrubs, and is typically found in arid, semi-arid, and subtropical shrubland environments. It is also frequently observed within clumps of spinifex.
Behavior and Defense
While primarily a nocturnal species, the northern spiny-tailed gecko may also be seen basking during daylight hours. A notable defense mechanism employed by this gecko is its ability to expel a harmless yet foul-smelling fluid from its tail when threatened, serving as a deterrent to predators such as birds. A bright palate color is another defense strategy observed in this species.
Diet and Reproduction
Information regarding the specific diet of Strophurus ciliaris is limited, but it is understood to consume arthropods, consistent with other gecko families. Observations have also noted instances of the gecko licking the exudates from wattle sap. The species is oviparous, meaning it reproduces by laying eggs, and typically lays a clutch of two eggs.
Geographic Range and Conservation
The northern spiny-tailed gecko is endemic to the interior of Australia. Its distribution spans from the northwest of New South Wales and western Queensland, extending through South Australia and the Northern Territory, and reaching into Western Australia. Despite threats such as habitat degradation caused by land clearing and invasive species like goats, the species is currently listed as Least Concern on the IUCN Red List. This favorable conservation status is attributed to its extensive geographic range, adaptability to various habitats, and the limited overall impact of current threats.
Subspecies
Two subspecies of Strophurus ciliaris have been identified: Strophurus ciliaris ciliaris and Strophurus ciliaris aberrans. Additionally, the species is recognized to have both a desert form and a tropical form.
