Sept. 2, 2026

Scientists from the Zoological Survey of India (ZSI), in collaboration with the ICAR-Central Marine Fisheries Research Institute (CMFRI) and international experts, recently discovered a new species of deep-sea skate named Dipturus dhritiae in the southeastern Arabian Sea.

About Dipturus dhritiae:

  • Dipturus dhritiae, commonly called the Arabian skate, is a new species of deep-sea skate.
    • A deep-sea skate is a flat, shark-related fish that lives on the dark bed of the ocean.
    • Deep-sea skates are particularly vulnerable to overfishing because they generally reproduce slowly, have few offspring, and take a long time to recover when their populations decline.
  • Dipturus dhritiae was discovered in the Arabian Sea off India’s southwestern coast.
  • One of its most noticeable features is five rows of thorn-like structures along its tail.
  • It is named after Dhriti Banerjee, the first woman Director of the ZSI.
