Why in the News
Scientists have discovered a new estuarine fish species, named Butis bargabhimae, in the Rupnarayan River near Tamluk.
About the Species
1. Classification
- Family: Butidae (gudgeon gobies)
- Habitat: Brackish water (estuaries)
- Found where rivers meet the sea
2. Discovery Process
- Time: 2022–2024
- Institutions: Tamralipta Mahavidyalaya and Vidyasagar University.
- Method:
- Field collection by local fishermen
- Morphological + DNA analysis
Unique Features
- Presence of interorbital scales (between eyes)
- Additional auxiliary body scales
- Distinct light and dark bands on pectoral fins
- DNA similarity only ~86% with closest relatives
- Confirms it as a new species
Naming Significance
- Named after Bargabhima, a local deity of Tamluk
- Reflects link between biodiversity and cultural heritage
Scientific Importance
- Taxonomic Clarity: Helped correct misidentification of similar species in:
- India
- Bangladesh
- Role of DNA Barcoding: Shows importance of genetic tools in species identification
- Hidden Biodiversity: Suggests many undiscovered species in Indian rivers and estuaries
