If you find yourself trekking through the mist-shrouded peaks of the Victorian Alps or the Tasmanian highlands, keep your eyes on the sun-drenched granite. You might just spot the Alpine Cool-skink (*Pseudemoia cryodroma*), a resilient little gem of the high country.
Identification
This is a small, slender skink, reaching a snout-vent length of about 60mm. Its dorsal surface is a glistening bronzy-brown or olive, often adorned with fine, dark flecks. Look closely for a dark mid-dorsal stripe and a distinct, pale-edged dark stripe running along its flanks. What truly sets the *Pseudemoia* genus apart is the "palpebral disc"—a transparent, window-like scale in the lower eyelid that allows the lizard to see even when its eyes are closed. Compared to the similar Grassland Cool-skink, the Alpine variety is more robust and lacks the vibrant green hues often seen in its lowland cousins.
Habitat & Range
True to its name, this specialist thrives in sub-alpine and alpine environments, typically above 1,000 meters. You’ll find them darting through snow-gum woodlands, sphagnum bogs, and rocky scree slopes across the Great Dividing Range and Tasmania. They are masters of the "micro-climate," seeking out north-facing rock crevices that trap the thin mountain sun.
Behaviour
These are heliothermic (sun-loving) baskers. On crisp mornings, you’ll see them flattened against dark rocks to absorb maximum heat. They are surprisingly bold for small lizards, though they will vanish into heath at the slightest shadow. Because mountain summers are short, they are viviparous—giving birth to 2–5 live young rather than laying eggs, which would likely freeze in the alpine soil.
Diet
The Alpine Cool-skink is an opportunistic hunter. It forages through leaf litter and low vegetation for small invertebrates, including spiders, beetles, and flies. During the height of summer, they are remarkably active, fueled by the seasonal boom of alpine insects.
Fascinating Fact
The specific epithet *cryodroma* literally translates to **"ice-runner."** It is one of the few reptiles capable of remaining active at near-freezing temperatures, occasionally seen scurrying across the edges of snowdrifts to reach a basking spot!
