What feature distinguishes keeled scales from smooth scales on a snake?
Answer
A distinct ridge running down the center
The texture of scales varies significantly across different snake families and species. Smooth scales result in a glossy appearance, while keeled scales are characterized by possessing a distinct ridge that runs longitudinally down the center of each scale. These variations in scale texture, along with the resulting patterns and coloration, are evolutionarily important, serving dual roles in providing cryptic camouflage to hide from predators or in aposematism, which acts as a warning signal of toxicity or danger to potential threats.
