The Iberian worm lizard is a reptile that has adapted to life underground and looks very like an earth worm. Variable background colour from pinkish grey, reddish brown to brown. The cylindrical body is covered with quadrangular scales forming rings. The head is small and looks little different to the body, the snout is rounded. Their vision is vestigial, the eyes being two tiny black dots beneath the skin, while its sense of smell and hearing are highly developed.
They can reach a length of 250mm (10 inches) and rarely more. When they feel threatened they move rapidly and coil around whatever obstacle they can, be it a natural stick or something artificial. If caught they will give small, but strong bites. It is not venomous.
From early research it seems the examples from the Sierra de Grazalema area belong to the new species Blanus mariae. (Formerly Blanus cinereus)
