How do the scales of *Rena humilis* compare to True Blind Snakes (Typhlopidae) regarding pattern uniformity?
Answer
Threadsnakes have slightly larger scales on the top than on the bottom
When compared to close relatives like the True Blind Snakes (Typhlopidae), *Rena humilis* (a threadsnake) exhibits subtle differences in scale arrangement despite sharing a generally smooth, glossy appearance. True Blind Snakes are typically noted for having scales arranged in a more uniform pattern across the entire body circumference. In contrast, *Rena humilis* exhibits a slight difference in size, possessing scales on its dorsal (top) surface that are somewhat larger than the scales found on its ventral (bottom) surface.
