Which physical feature most distinctly differentiates a vole from a mouse?
Answer
The length and texture of the tail
The tail serves as a primary diagnostic feature when distinguishing voles from mice. While mice possess long, often scaly tails that can measure nearly half their body length, voles are characterized by significantly shorter, furry tails. This difference is linked to their respective lifestyles; a long, scaly tail would be impractical and potentially dangerous for a vole navigating tight, subterranean environments.
