ALPINE WATER SKINK Eulamprus koscioskoi (Kinghorn, 1932)
This 22 cm lizard is found in alpine areas and very high mountain areas of NSW and adjacent Victoria, at altitudes above 1000 metres.
This lizard is common on the slopes of Mt.Kosciosko and is found active during the day around the seepages and small creeks that flow down the slopes of the mountain. Elsewhere it occurs in similar habitats, in proximity to water.
The Alpine Water Skink is active at temperatures too cold for most other reptiles, and can often be seen active around snow drifts or while it is hailing. Although mainly insectivorous, this lizard will feed on some plants.
This lizard is live bearing and gives birth to about four young in mid to late summer.
The gestation period is believed to be about 11 weeks.

The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
