They are also known as "Shinglleback skinks" they live in Outback Australia.
The member of their family that I remember most is the "Bluetongue lizard" which, as you may guess, has a blue tongue.
They live in all habitats and States of Australia, including backyards.
We used to see them at the beach.
Quite big, about 30 centimetres ( 1 foot) long.
