Why in News?
Nyctibatrachus kali, commonly known as the Kali Night Frog, is in the news because researchers and forest department staff officially announced its discovery as a new species on March 27, 2026.
Taxonomy and Discovery
- Genus: Nyctibatrachus (night frogs), family Nyctibatrachidae; morphologically cryptic, resembling Kumbara Night Frog (Nyctibatrachus kumbara) but distinct in advertisement calls, genetics, and evolutionary lineage.
- Found by tracking faint, repetitive calls blending with forest sounds near streams in central Western Ghats.
- Research led by Aravind CK (PhD scholar) and team, involving DNA analysis and sound differentiation from 34 existing Nyctibatrachus species.
Physical Characteristics
- Cryptic species: Closely mimics known night frogs, making visual ID hard; differentiated by vocalizations and genetics.
- Produces a distinctive "tock" or wood-chopping sound, key to its detection.
- Torrent-dwelling, adapted to fast-flowing streams in evergreen forests and shola-grasslands.
Habitat and Distribution
- Central Western Ghats, specifically Kali Tiger Reserve (Uttara Kannada, Karnataka), bordering Goa; near Kali River.
- Thrives in rain-soaked forest streams, a mosaic of tropical evergreen, shola-grassland, and semi-evergreen vegetation.
- Endemic to India, adding to over 470 amphibian species (5.3% of global total).
Conservation Notes
- Highlights Western Ghats as a biodiversity hotspot with undiscovered species despite heavy study.
- Faces risks from habitat degradation, climate change, diseases, and potential human activities.
- Praised by Karnataka officials (Kumar Pushkar, IFS) for boosting conservation awareness and staff involvement.
