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] SpeciesThe genus contains the following species:[6][7]
