New caecilian species discovered in Northern Western Ghats
Researchers discover a new subterranean caecilian species, named Gegeneophis chandgadi, in the Northern Western Ghats. The finding reinforces the Northern Western Ghats as a critical caecilian biodiversity hotspot and micro-endemic zone.
Gegeneophis chandgadi:
| Dimension | Key Details |
|---|---|
| Taxonomic position | Belongs to the family Grandisoniidae under the order Gymnophiona, class Amphibia. |
| Etymology | Named chandgadi in honor of the Chandgadi dialect of Marathi spoken in the Chandgad region. |
| Morphology | It is a subterranean, limbless, and completely silent amphibian with a cylindrical, pinkish-brown body adapted for burrowing in soil and leaf litter. |
| Common misidentification | It is often misidentified by locals as an earthworm or a small snake. |
| Habitat | Inhabits non-protected, mixed agricultural and residential landscapes rather than restricted primary forests. |
| India amphibian and caecilian counts | India records 42 caecilian species out of 458 total amphibian species. |
| Genus Gegeneophis endemism | Out of 12 known species in the endemic genus Gegeneophis, 11 are strictly endemic to the Western Ghats. |
| Western Ghats concentration zone | Species in genus Gegeneophis comprise a high concentration clustered in the transitional belt between Maharashtra, Goa, and Karnataka. |
| Survey limitation | Caecilians live predominantly underground, rendering conventional visual biodiversity surveys ineffective. |
| Drivers of “silent extinction” risk | Unrecorded species face silent extinction due to habitat fragmentation, chemical pesticide use, soil compaction, and rural development before being scientifically documented. |
| Role of Traditional Ecological Knowledge (TEK) | The discovery relies heavily on the traditional environmental familiarity and assistance of local villagers. |
| Citizen science and community partnership | It highlights the role of citizen science and indigenous community partnership in biodiversity conservation outside Protected Areas (PAs). |
