Blanus is a genus of amphisbaenians found in the Mediterranean region of Europe and North Africa.[2] Like other amphisbaenians, Blanus are specialized for a subterranean existence, with a long, slender body, reduced limbs, and rudimentary eyes. The skull is powerfully constructed, allowing the animal to push through soil to create a burrow. The jaws are well-developed, with large, recurved teeth and a pair of canine-like teeth in the upper jaw.
Five extant species are currently known. The relationships of Blanus to other worm-lizards are not clear. The genus was formerly included in the Amphisbaenidae. More recent analyses suggest that blanids are more primitive, and are either related to Bipes [3] or represent an even more ancient lineage.[4]
A number of fossils from Europe have been referred either to Blanus or to the Blanidae.[5]
