Scientists from the Zoological Survey of India (ZSI), in collaboration with ICAR-CMFRI and international experts, discovered a new deep-sea skate species, Dipturus dhritiae, in the southeastern Arabian Sea. The species, named Arabian Skate, was collected at depths of 400â600 metres off Kerala and the Wadge Bank during the Deep Ocean Mission. It had remained unidentified for over 40 years and was earlier misidentified as Dipturus springeri. The species can grow up to 131.5 cm and has five distinct rows of thorns along its tail. Genetic analysis showed 3.8â4.7% divergence from its closest known relative, the Travancore Skate. It is named after Dhriti Banerjee, ZSIâs first woman Director.
