Contrary to its outward appearance, the sluggish worm is neither a worm nor a snake—it is a legless lizard! Also known as deaf adder or blindworm, this species is common throughout Eurasia. Slow worms have a V shape on their heads and scales that partially cover their eyes, giving them a lidded appearance.
They also have distinctive black or dark brown zig-zag markings on their backs, which help them differentiate from other species of adders. In heathland, tussocky grassland, woodland edges, and rides, slow worms can be found searching for invertebrates to eat and a sunny area to sunbathe.
