What habitat requirement defines a worm snake as 'fossorial'?
Answer
Adaptation for digging and living beneath the surface
The term fossorial is defined specifically as describing animals adapted for digging and living beneath the surface layer of the ground. This adaptation dictates nearly every aspect of the worm snake's existence, from its preferred soil type to its diet and vulnerability to surface predators. Because they are fossorial, they require loose, friable soil that allows them to tunnel easily, unlike hard clay or compacted earth. This subterranean existence also means they seek out consistent shade and moisture found underground or directly beneath cover objects, contrasting sharply with surface-dwelling reptiles.
