Carinascincus ocellatus (Gray, 1845)

Scientific Nomenclature

The spotted skink, scientifically named Carinascincus ocellatus, is sometimes referred to as the ocellated cool-skink or ocellated skink.

Endemic Range

This species of skink is endemic to Tasmania, Australia.

General Biological Traits

It is a ground-dwelling, viviparous species that typically inhabits rocky environments.

Geographic Distribution

It is widespread across northern and eastern Tasmania, and also occurs on the eastern Bass Strait islands.

Recorded Site

It is frequently encountered at Arthurs Lake in Tasmania’s Central Highlands.

Altitudinal Gradient Impacts

Populations of spotted skink are distributed along an altitudinal gradient, and differences in thermal conditions across this gradient impact the species’ body temperature regulation and reproductive activity.

Low-Mid Altitude Thermal Traits

Spotted skinks at low to mid altitudes can reach their optimal body temperature throughout the year.

Low-Mid Altitude Reproductive Cycle

For these individuals, vitellogenesis and ovulation mostly occur in spring, and gestation takes place in summer.

High Altitude Thermal Traits

By contrast, spotted skinks living at higher, subalpine altitudes have difficulty maintaining their preferred body temperature during autumn, and these skinks typically undergo ovulation and parturition one month later than other members of the species.
