Key factual points
- A new freshwater crab species, Ghatiana karnataka, has been scientifically described from Mookambika Wildlife Sanctuary, Udupi, Karnataka.
- It was discovered by a beat forester and described with a scientist from the **Zoological Survey **of India (ZSI).
- Location: Mookambika Wildlife Sanctuary, Central Western Ghats, Karnataka.
- It is the 15th known species of the genus Ghatiana in the Western Ghats.
- Eight species, including the newly described one, are endemic to Karnataka.
- Appearance: Dark-purple body with light-pink claws.
- Habitat: Perennial streams and evergreen/semi-evergreen forests.
- During monsoon, it occurs around laterite rocks; in other seasons, it shelters in moist tree cavities.
- Freshwater crabs are sensitive to habitat alteration and pollution.
- The new species can therefore serve as an indicator of relatively undisturbed freshwater–forest ecosystems.
- The discovery also highlights the still-underexplored biodiversity of the Western Ghats.
- Map linkage: Western Ghats → Karnataka → Udupi → Mookambika Wildlife Sanctuary.
Prelims traps
- Distinguish the immediate development from the permanent mandate or structure of the institution concerned.
- Revise exact names, dates, locations and legal or institutional terms from the source points; do not infer facts not stated there.
