Though snake-like in appearance, the Sheltopusik is actually one of several species of lizards that has developed a long, slender and seemingly limbless bodies (although on close inspection they do possess two tiny hindlimbs) in order to move through underground burrows and other tight spaces; key traits that distinguish these lizards from true snakes include the presence of eyelids and external ear holes, wide tongues with no forked endings and the absence of enlarged scales on the belly, limiting their ability to generate friction and meaning they struggle to slither across smooth surfaces. Found mainly in warm, dry grasslands in central Asia and southeastern Europe, Sheltopusiks are carnivorous but lack the ability to envenomate or constrict their prey, instead subduing insects, snails and small vertebrates using their powerful jaws lined with broad, rounded teeth. Members of this species also use their jaws to defend themselves when threatened, but in extreme cases when this fails to deter an attacker they may shed their tail, which can then continue to break into smaller pieces after separating from the body (this "fracturing" has led some to refer to the Sheltopusik and its relatives as "Glass Lizards".)
