What key trait differentiates Worm Snakes from young Black Racers?
Answer
Smooth scales (Racers are keeled)
When attempting to distinguish a Worm Snake from other small, dark burrowing snakes, such as a young Black Racer, scale characteristics are a definitive differentiator. Worm Snakes possess smooth scales which minimize friction underground. In contrast, Black Racers are noted to have keeled scales, meaning their scales feature a central ridge. This difference in scale texture is an immediate visual cue that helps separate the fossorial *Carphophis* species from other similarly sized reptiles encountered near the surface, even if the coloration appears similar upon quick inspection.
