Blanus, also known as worm lizards, are a genus of amphisbaenians found in the Mediterranean region of Europe and North Africa.[1] Like other amphisbaenians, Blanus species are specialized for a subterranean existence, with long, slender bodies, reduced limbs, and rudimentary eyes. Their skulls are powerfully constructed, allowing them to push through soil to create a burrow. Their jaws are well-developed, with large, recurved teeth and a pair of canine-like teeth in the upper jaw.

Four to seven 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[2] or represent an even more ancient lineage.[3]

A number of fossils from Europe have been referred either to Blanus or to the Blanidae.[4]
