Types of earth snakes

Rhinophis is a genus of shieldtail snakes in the family Uropeltidae, a group of small, primitive burrowing snakes found only in southern India and Sri Lanka. The family name Uropeltidae means 'tail shield', a reference to the most distinctive feature shared across the group: a hardened, often roughened or flattened plate of scales at the tip of the tail. Rhinophis is one of the larger genera in this family, and our database includes 20+ species.

These are fossorial snakes, meaning they live underground and are built for digging. Members of Rhinophis have a narrow, pointed snout adapted for pushing through soil, a cylindrical body, very small eyes, and smooth, glossy scales that reduce friction as they move through the earth. The genus name itself comes from the prominent rostral shield on the snout, which the snake uses like a wedge. The tail ends abruptly in the characteristic keeled or spiny shield. They are generally small snakes, most measuring well under a foot in length, with bodies that often show iridescent dark coloration and pale or yellowish markings on the underside.

Rhinophis is restricted to South Asia. The center of its diversity is Sri Lanka, with additional species in the Western Ghats and other parts of peninsular India. Typical habitat is moist soil in forests, plantations, gardens, and agricultural land, especially areas with loose, damp earth where the snakes can tunnel. Because they live below the surface, they are rarely seen unless turned up by digging, flooding, or heavy rain that drives them out of the ground.

These snakes are harmless to people. They are non-venomous and pose no danger to humans. Shieldtails are not built to bite defensively in any meaningful way; their small mouths and gentle nature mean a person is far more likely to mistake one for an earthworm than to feel threatened by it. They feed mainly on earthworms and other soft-bodied soil invertebrates, which they hunt underground. When threatened, a shieldtail may hide its head in its coils and present the blunt, armored tail shield as a decoy, a behavior thought to protect the vulnerable head from predators.

Reproduction in Rhinophis and other uropeltids is live-bearing rather than egg-laying, with females giving birth to small litters of fully formed young. Their secretive, subterranean lifestyle means much of their detailed ecology and behavior remains poorly documented, and new species are still being described as researchers study the soils of India and Sri Lanka more closely. For anyone who encounters one, no first aid or medical concern applies; if there is ever genuine uncertainty about a snake or a bite from any wild animal, contact local emergency services or US Poison Control at 1-800-222-1222.
