MOUNTAIN DRAGON Amphibolurus diemensis (Gray, 1841)
This 18 cm lizard, is found along the coast and ranges of south-east Australia, south of Wyong (NSW), and scattered highland areas in the New England region (NSW). Victorian specimens seem to grow larger than their NSW counterparts.
Colour varies widely between individuals even within a given locality. The two sexes also have different patterns. Commonly confused with other types of dragon, the Mountain Dragon may be distinguished by the blue interior of the mouth.
The Mountain Dragon is most common in low scrub, heaths, and similar habitats. It is insectivorous. In cold areas this species may be found in a nearly frozen state in winter. The female lays about 2-8 eggs in a sheltered spot in early summer. Hatchlings measure about 3 cm and are generally dull in colour.
