What texture characterizes the scales of *Rena humilis* that aids its subterranean movement?
Answer
Distinctly smooth and possess a high degree of glossiness or shine
The scale texture of the Western Blind Snake is a notable feature setting it apart from many other reptiles whose scales may be keeled or lack luster. The scales covering *Rena humilis* are characterized by being very smooth and possessing a high degree of glossiness or shine. This slick, non-abrasive surface quality is highly functional, as it actively minimizes friction when the snake is burrowing or moving through the substrate underground. This smoothness is essential for maintaining efficiency while engaging in its subterranean activities.
