Forester's Keen Eye Uncovers Hidden Crab Species
16 Aug
Summary
- New freshwater crab species Ghatiana karnataka discovered in Mookambika Wildlife Sanctuary.
- The male crab features a dark-purple body with a distinctive light-pink V-shaped marking.
- This discovery highlights the region's rich, yet undocumented, biodiversity waiting to be uncovered.
A new species of freshwater crab, Ghatiana karnataka, has been scientifically described following its discovery in the Kollur range of Mookambika Wildlife Sanctuary. Beat forester Ajmeer K's attention was captured by the crab's distinct coloration and movement during a forest patrol last year. This led to a collaboration with Santanu Mitra from the Zoological Survey of India, resulting in a research paper detailing the new species.
The male Ghatiana karnataka exhibits a predominantly dark-purple carapace with a unique light-pink to mauve V-shaped marking, while females display grey-violet and dark grey-brown hues. The species is endemic to the Western Ghats, and this discovery brings the total number of Ghatiana species recorded in Karnataka to eight. Initial findings suggest its presence across a 35-km stretch within moist evergreen and semi-evergreen forest habitats.
Associated with perennial river systems, these crabs inhabit crevices in boulders, rock holes, and tree cavities. They feed on decaying plant matter and other organic material. The discovery serves as a potent reminder of the vast, undocumented biodiversity within India's natural landscapes. Forest department officials have pledged continued support for staff engaged in biodiversity research.
