Northern Grass Skink

Oligosoma polychroma

Northern Grass Skink

LOCATION: Native to New Zealand and found in Te Mata Park.

BEHAVIOUR: All lizards are cold blooded animals. This means that, unlike in mammals, lizards absorb heat from the environment rather than generate it internally.

Many lizards bask in the sun to get warm, and if they aren’t warm enough they have difficulty moving. The body temperature that a lizard can achieve has a profound effect on important life-traits – low temperatures can lengthen pregnancy, and can even result in the unborn baby’s (neonate’s) death.

The most common food of Northern grass skinks is invertebrates, namely beetles, spiders, and the caterpillars of moths and butterflies. They also eat a small amount of seeds and fruit. (DOC)

HABITAT: Northern grass skinks are avid baskers. They seek sun and prefer sunny habitats. They often minimise the risk of predation by exposing only small parts of their body at one time, still remaining well hidden.

Northern grass skinks love sunny rock piles and tumbles that have plenty of crevices. Not only are they great for basking in safe spots, but rock retains heat to keep them warm during cold spells.

Northern grass skinks prefer grasslands (especially tall grass species or rank grass), scrublands and vinelands rather than forests. They love dry, open areas with lots of places to bask and lots of cover to hide under. (DOC)
