How many rows of smooth scales do Worm Snakes possess around their midbody?
Answer
13 rows
For herpetological identification, the scale configuration provides a reliable diagnostic feature for the Worm Snake genus. Most sources agree that these snakes consistently possess exactly 13 rows of smooth scales when measured around their midbody. This specific count is considered a reliable identifier within the group. This number is structurally significant as it maintains the necessary integrity for burrowing without adding excessive bulk that would impede movement within narrow soil tunnels, differentiating them from other snakes that might exhibit higher counts, such as 15 or more scale rows.
