Description
Northern Spiny-Tailed Gecko
Scientific Name: Strophurus ciliaris
Common Name: Northern Spiny-Tailed Gecko, Northern Spiny Gecko, Eyelash Spiny-Tailed Gecko
Species Overview
Size: Adult Northern Spiny-Tailed Geckos typically reach 4.5–5.5 inches (11–14 cm) in total length, including the tail. They are small, slender geckos with fine scalation and a distinctive spiny tail lined with small, pointed tubercles.
Appearance: Strophurus ciliaris is one of Australia’s most striking gecko species, featuring a pale grey, tan, or sandy base colour covered in fine spots or reticulated markings of darker brown or black. The tail is covered in prominent spines, and individuals from some populations have small raised scales above the eyes that resemble eyelashes—giving rise to the common name “Eyelash Gecko.” The underside is pale cream or white, and the eyes are large and silver to amber with vertical pupils. When threatened, this species can secrete a sticky, odorous defensive fluid from the tail, an adaptation unique to the genus Strophurus.
Distribution: Found across northern and central Australia, particularly in arid and semi-arid regions of Western Australia, the Northern Territory, and Queensland.
Habitat: In the wild, Northern Spiny-Tailed Geckos inhabit dry woodlands, spinifex grasslands, and arid shrublands. They are primarily arboreal, often found perched on shrubs or small trees, where they hunt insects at night and rest in shaded crevices during the day. In captivity, they thrive in semi-arid, well-ventilated enclosures with both vertical climbing areas and open ground.
Behaviour: This species is nocturnal and semi-arboreal, becoming active after dusk. They are calm when undisturbed but may raise their tails and exude defensive fluid if threatened. They are alert, observant, and relatively hardy once acclimated, making them excellent display geckos for keepers experienced with arid species.
Captive Care
Enclosure: Provide a vertically oriented or mixed-use terrarium measuring at least 18 inches × 18 inches × 18 inches (45 × 45 × 45 cm) for a single adult or pair. Use a sandy soil mix or desert substrate with scattered rocks and sturdy branches for climbing. Include multiple hides and elevated perches to encourage natural behaviour.
Temperature & Humidity: Maintain daytime temperatures between 80–88°F (27–31°C) with a basking area near 92°F (33°C). Nighttime temperatures can safely drop to 68–72°F (20–22°C). Keep humidity low to moderate (40–55%), with light misting once every few days to provide drinking water. Always ensure excellent ventilation.
Lighting: Although nocturnal, Strophurus ciliaris benefits from low-level UVB lighting (2–5%) to support calcium metabolism and maintain healthy activity patterns. A 12-hour light/dark cycle with soft ambient light is ideal.
Diet: Offer a diet of small, gut-loaded insects such as crickets, roaches, silkworms, and black soldier fly larvae. Feed adults 3–4 times per week and juveniles more frequently. Dust all prey with calcium and multivitamin supplements regularly.
Behaviour in Captivity: Northern Spiny-Tailed Geckos are hardy, inquisitive, and highly active during the night. They adapt well to captivity when provided stable temperatures and a dry, open environment. Their calm temperament and unique defensive behaviour make them particularly fascinating display reptiles.
Special Considerations: Avoid high humidity and stagnant air, as these can lead to respiratory issues. Do not handle frequently—while generally tolerant, their small size and delicate tails make them vulnerable to stress. Provide regular access to light misting or shallow water droplets for hydration.
Taxonomy Note
The Northern Spiny-Tailed Gecko (Strophurus ciliaris) belongs to the family Diplodactylidae and is one of the most recognized species within the Strophurus genus. This genus is endemic to Australia and known for its distinctive spiny tails and unique chemical defense mechanism. S. ciliaris has two recognized subspecies: S. c. ciliaris (northern) and S. c. aberrans (southern), with the northern form typically displaying lighter colours and finer patterning.
Genetics Note
There are currently no recognized morphs or selectively bred variants of Strophurus ciliaris. Natural variation occurs in colour tone, pattern density, and the prominence of tail spines, primarily influenced by geographic locality. These differences are naturally occurring adaptations rather than the result of selective breeding.
