The Eastern Blue-tongue is silvery-grey with broad dark brown or blackish bands across the back and tail. Individuals on the coast usually have a black stripe between the eye and the ear which may extend along the side of the neck. The Blotched Blue-tongue is dark chocolate brown to black with large pink, cream or yellow blotches on the back, and a tail banded in the same colours.
The Eastern Blue-tongue can grow to almost 600 mm in total length, of which about 360 mm is head and body.
Blue-tongues usually live in open country with lots of ground cover such as tussocky grasses or leaf litter. They shelter at night among leaf litter or under large objects on the ground such as rocks and logs. Early in the morning blue-tongues emerge to bask in sunny areas before foraging for food during the warmer parts of the day. Like all lizards, blue-tongues do not produce their own body heat, and rely on the warmth of their surroundings to raise their body temperature. Blue-tongues maintain a body temperature of about 30°C – 35°C when active. During cold weather they remain inactive, buried deep in their shelter sites, but on sunny days they may emerge to bask
