Blindworm is the common name of a type of legless lizard that lives in Europe, western Asia, and northern Africa. A blindworm is not blind, nor is it a worm. It looks like a snake, but it is easily identified as a lizard because of its movable eyelids and fragile tail. People sometimes call it slowworm. It grows to about 20 inches (50 centimeters) in length. A blindworm crawls with slow, snakelike movements and eats slugs. The blindworm is related to the glass lizard.
