What coloration feature often distinguishes the belly region of *Rena humilis* from its dorsal side?
Answer
The belly region is frequently described as being lighter in coloration
While the dorsal side of the Western Blind Snake displays a range of muted, earthy tones such as brown and gray, sometimes with dark speckling, the coloration of the underside presents a consistent difference. The belly region, or ventral side, is typically noted as being lighter in color compared to the upper (dorsal) surface of the snake. This lighter belly coloration contributes to the snake's overall camouflage when it occasionally surfaces, helping it blend with leaf litter or disturbed soil, even though its primary habitat is hidden.
