Three-toed Snake-tooth Skink  |  

The Three-toed Snake-tooth Skink has reduced limbs, each with three digits. Snout-vent length (SVL) is reported as 180 mm, 195 mm and 231 mm. Two hatchlings had a SVL of 60 mm and 58 mm and a total length of 113 mm and 112 mm. Measurements of nine intact specimens had tails that were 9–45% longer than their SVL, which suggests a total length of 483–565 mm. Adults usually have a dark eye-patch, dark ear markings and a distinct wedge-shaped, pointed pale snout. Dorsal colour in adults is generally brown to yellowish brown or grey, sometimes with a vague indication of the dark juvenile bands, and side and belly scales paler brown. Individual flecked scales are streaked with dark brown, a black collar and often small, scattered dark brown spots on the back, with dark brown streaks on the throat. Adults from Cooloola and Fraser Island have been described as ‘immaculate bluish grey’. Ventral scales are normally greyish and dark-edged to form a fine reticulum-like pattern describes an adult bluish-grey colour form from Cooloola as having white dark-edged ventral scales. Juveniles are cream to brown dorsally with prominent, irregular transverse dark bands that are more conspicuous anteriorly, often absent posteriorly. Juveniles have dark patches centered on the eye and ear depression, the snout is cream, and the scales on the sides of the body are dark-edged, forming irregular longitudinal streaks.
