Ornate Skink

Ornate skinks have a snout–vent length of up to 84 mm (3.3 in), and can weigh as much as 11.5 g (0.41 oz). The species has a short snout, a teardrop marking beneath its eyes, and black markings along the neck and shoulders. Individuals of the species vary in terms of the shade of brown on their bodies and patterning. The population found on Manawatāwhi / Three Kings Islands is morphologically distinct, having longer snouts, more slender bodies, and less contrasting underside surfaces. Specimens from the Northland Region can also have more distinct patterns and markings. Ornate skinks can be identified by the white or yellowish "teardrop" edged with black, below each eye, and as the species is relatively larger compared to other visually similar species, such as the copper skink.

The species is widespread across the North Island of New Zealand, except for the Hawkes Bay area. Additionally, the species can be found on many offshore islands near the North Island, including Manawatāwhi / Three Kings Islands, Great Barrier Island, and Little Barrier Island. This species was once widespread through much of the North Island and on many offshore islands in the Hauraki Gulf and north of the Coromandel Peninsula. Habitat destruction and predation by introduced species has now reduced their range to scattered localities throughout the North Island as far south as Wellington, as well as on the Three Kings Islands, Great Barrier Island, and a few other offshore islands.

The species prefers to live in damp or humid environments, typically forests and grasslands, and areas with significant amounts of damp leaf litter. It is primarily active during twilight. Ornate skinks typically feed on small invertebrates. Ornate skinks mate in spring, giving birth to between four and six individuals over summer, typically between January and February. Ornate skinks co-exist widely with copper skinks, and at selected localities with robust skinks, Mokohinau skinks, McGregor's skinks, Poor Knights skinks and on Great Barrier and Little Barrier Islands, marbled skinks. Ornate skinks are not currently known to co-exist with Whitaker's skinks.
