Anguis fragilis (Slow Worm)

Synonyms: Anguis gamma; Anguis orvet

Wikipedia Abstract

The Anguis fragilis, or slow worm, is a limbless lizard native to Eurasia. It is sometimes called a blindworm. Its German name, "Blindschleiche," is derived from the Old High German plintslîcho meaning "blinding creeper", perhaps because of its lustrous scales.
