В Аравийском море обнаружен новый вид глубоководного ската, скрытый от науки десятилетиями

Indian scientists have discovered a new species of deep-sea skate in the Arabian Sea. The fish was found at depths of around 400 to 600 metres. Named Dipturus dhritiae, the skate can grow to about 1.3 metres long. Scientists from the Zoological Survey of India (ZSI) and other research institutions identified it using physical features and DNA analysis. The discovery is significant because specimens had been collected for more than four decades. They were previously mistaken for another skate species. A new species from the Arabian Sea The newly identified skate lives in deeper Arabian Sea waters. It has been recorded off Kerala and around the Wadge Bank. The fish has a flat body and a distinctive tail. Researchers found five rows of thorn-like structures along its tail. These features helped distinguish it from other known skates. Species named after Dhriti Banerjee The species was named Dipturus dhritiae in recognition of Dhriti Banerjee, the first woman Director of the ZSI. But the discovery is about more than one fish. It is a reminder that India's deep waters may still contain species scientists have yet to properly identify. DNA confirmed the discovery Physical appearance alone was not enough to identify the fish. Researchers compared it with closely related species. They also conducted genetic analysis. The DNA showed a clear difference from its closest known relative, the Travancore skate. The genetic divergence was around 3.8% to 4.7%. This helped confirm that the fish represents a separate species. A species hidden for decades The discovery has an unusual twist. Scientists had encountered specimens of the skate for decades. However, they had been classified as another species. Detailed examination changed that understanding. It shows how species can remain hidden in plain sight. Modern genetic tools can reveal differences that may not be obvious from appearance alone. Why does the deep sea matter? The discovery highlights how little is known about India's deeper marine ecosystems. The deep sea is difficult to explore. It is dark, cold and under immense pressure. Many species living there are rarely seen. Others can closely resemble known species. This makes DNA analysis and detailed taxonomic studies crucial for identifying hidden biodiversity. Conservation efforts for this species The finding also raises conservation concerns. The new skate has been recorded as bycatch in deep-sea shrimp trawling. Skates can be vulnerable to fishing pressure. Many grow slowly and reproduce slowly. Their populations can therefore take longer to recover. The discovery also highlights India's Deep Ocean Mission and its efforts to explore poorly understood marine environments. Discover the latest Business News, Sensex, and Nifty updates.
