Palearctic worm lizards or desert ringed lizards Trogonophidae
Trogonophids are found in North Africa, the Horn of Africa, the Arabian Peninsula, and western Iran. Trogonophids are limbless, carnivorous, lizard-like reptiles highly modified for burrowing. They construct their tunnels with an oscillating motion that forces soil into the walls. Unlike other amphisbaenians, their teeth are fused to their jaws, rather than lying in a groove.
