Overview
The Jewelled Gecko (Strophurus elderi) is an enchanting miniature diplodactylid gecko exquisitely adapted to the unforgiving desert interior of central Australia. Known alternatively as the Starry Gecko, its slender, velvety charcoal body is embellished with a celestial constellation of pure white rosettes encircled by dark rings, perfectly mimicking the sharp needles and shadows of the spiny desert grasses in which it spends its entire life.
Biology and Physical Characteristics
Measuring barely 3 inches in total length, Strophurus elderi is a master of specialized crypsis. Its dorsal surface ranges from ash grey to deep chocolate, speckled with intricate white spots that break up its body outline. Its eyes are large and lidless, cleaned with a specialized tongue swipe, and feature exquisite golden-ringed pupils. Its prehensile tail houses specialized caudal glands capable of squirting an unpleasant, sticky fluid when threatened.
Behavior and Ecology
Strophurus elderi is an obligate spinifex specialist, rarely ever touching bare ground. By day, it retreats deep within the dense, needle-sharp labyrinth of living Triodia grass hummocks where temperatures remain cool and predators cannot reach. At night, it climbs to the outer spires to ambush foraging termites and small insects. If confronted by a predator such as a pygmy monitor or bird, it arches its spiny tail and squirts a foul-smelling, unpalatable liquid from specialized dorsal caudal pores.
Conservation and Human Impact
Evaluated as Least Concern by the IUCN, Strophurus elderi maintains vast, continuous populations across the uninhabited desert expanses of the Great Victoria, Gibson, and Simpson Deserts. The primary ecological threat is large-scale, intense wildfire that consumes extensive tracts of old-growth spinifex grass, temporarily stripping away its essential shelter until the hummocks regenerate over several years.
Interesting Factoid
When cornered by a predator, the Jewelled Gecko can project a sticky, foul-tasting viscous stream from pores along its tail that rapidly hardens into rubbery threads, gumming up the mouth or feathers of the attacker.
