boldly patterned skink of Otago schist

Size
Length: 25–30 cm
Lifespan
15–20 years
Diet
Insectivorous - feeds on insects, wētā, and small lizards. One of New Zealand's rarest lizards, found only in Central Otago. Critically endangered due to habitat loss and predation by introduced mammals.
Habitat
Tussock grasslands and rocky outcrops in Central Otago. A large, distinctive skink that basks on rocks and hides in crevices. Requires rocky habitats with abundant sun exposure and nearby cover.
Range
New Zealand - found only in Central Otago, in the tussock grasslands and rocky outcrops of the Macraes Flat area. One of the most restricted ranges of any New Zealand lizard.
Endemism
Endemic
Main Threats
Predation by introduced cats, stoats, ferrets, and hedgehogs is the primary threat. Also threatened by habitat loss from farming and fire. Classified as Nationally Critical, one of New Zealand's rarest lizards with fewer than 2,000 individuals remaining.
Population
One of New Zealand's rarest lizards, found only in Central Otago. Classified as Nationally Critical, with fewer than 2,000 individuals remaining. Intensive predator control and captive breeding programmes are underway to prevent extinction.
Conservation Status
Nationally Critical
If a common garden skink is a compact car, the Otago Skink is a luxury off-road tank. Reaching up to 30 centimetres in length, they are the "heavyweights" of the New Zealand skink world. They do not just scuttle; they command the rock. Their skin is a stunning mosaic of black, grey, and olive-green blotches that mimic the lichens growing on the schist, making them nearly invisible until they move. Unlike the smooth, glossy texture of many other skinks, the Otago Skink has a rugged, "armoured" appearance that looks as though it was carved directly from the stone it inhabits. The Otago Skink is a dedicated sun-worshipper. In the cool climate of the south, they spend a significant portion of their day "basking" on the flat surfaces of schist rocks to raise their body temperature. However, they are always "on a hair-trigger". At the slightest hint of a shadow - be it a passing hawk or a curious human - they vanish into deep rock crevices with a speed that is startling for an animal of their bulk. These crevices are their fortresses, providing protection from predators and a stable temperature during the extreme Otago winters. They are surprisingly long-lived, potentially reaching 40 years or more, meaning a single skink may inhabit the same rock tor for nearly half a century. Their diet is as robust as their physique. While they are primarily insectivores, feasting on beetles, moths, and spiders, they are also opportunistic "fruit-eaters". They play a vital role in the ecosystem by consuming the small berries of native shrubs like Melicytus and dispersing the seeds across the rocky landscape. Interestingly, they are also known to scavenge, occasionally feeding on the remains of small birds or even other lizards. Like most New Zealand reptiles, they give birth to live young (usually twins or triplets) in mid-to-late summer, ensuring their offspring are born ready to navigate the treacherous world of the high country. The survival of the Otago Skink is currently dependent on "intensive care" conservation. Because they are large, slow-breeding, and highly visible to predators like feral cats and ferrets, their numbers plummeted during the 20th century. Today, they are protected by massive "predator-proof" fences and intensive trapping networks that create safe havens among the rocks. They are the "Dragons of the South", a remnant of a prehistoric era when New Zealand's drylands were teeming with giant, sun-loving reptiles. To see one today is a privilege - a rare glimpse of a master survivor holding its ground on the ancient, golden altars of Otago.
