What is the primary function of the sharp spine found at the terminus of the Western Blind Snake's tail?
Answer
To jab into tunnel walls to gain purchase or leverage for movement
The tail of *Rena humilis* terminates in a small, sharp spine, which is a crucial structural element supporting its fossorial lifestyle. Since the snake spends most of its life underground moving through confined tunnels, this spine is utilized as a physical aid for locomotion. When navigating tight spaces, the snake can forcefully push or jab this spine against the surrounding soil or tunnel walls. This action provides essential purchase or leverage, allowing the snake to effectively push itself forward or maintain stability while maneuvering beneath the surface, an essential feature given its slender, cylindrical body shape.
