Scientists confirm new deep-sea shark species off Kerala after decades of misidentification
Indian researchers have identified a previously unrecognised deep-sea shark, named Echinorhinus roinee. Specimens caught off Kerala had been wrongly grouped with the Atlantic bramble shark for decades. Scientists from the Zoological Survey of India and ICAR-Central Marine Fisheries Research Institute confirmed the species through physical examination and mitochondrial DNA analysis, which revealed a distinct Indian Ocean lineage. The shark can reach lengths of up to three metres. The finding underscores how much of India's deep-sea biodiversity remains unexplored and why precise species identification matters for marine conservation.
