Scientists associated with the Zoological Survey of India have identified a new marine fish species,

The new species, named Ariosoma cmfriense, was identified by scientists from the ICAR-Central Marine Fisheries Research Institute in Kochi. The specimen was collected from waters off Kollam at a depth of approximately 300 metres in January 2026 as part of research associated with India’s Deep Ocean Mission.

The two species, Ingerana aizawl and Duttaphrynus phawngpui, were described in separate scientific papers published in September 2026. Together, the discoveries underline how much of the amphibian diversity of Mizoram and the wider Indo-Burma biodiversity region remains incompletely documented.

Schizopygopsis waddellii belongs to the family Cyprinidae, which includes carps and many other freshwater fishes. It is part of a group adapted to the cold, oxygen-poor and highly seasonal waters of the Tibetan Plateau and adjoining Himalayan region.

Scientists from the ICAR-National Bureau of Fish Genetic Resources (ICAR-NBFGR), Lucknow, have described the new species as Chromis veneta sp. nov., following detailed genetic and morphological studies of blue-green chromis collected during marine biodiversity research in Lakshadweep.

Named Apristurus drona, the new shark was described by Sweta Beura, K. K. Bineesh and Dhriti Banerjee of the Zoological Survey of India. Their study was published on June 9, 2026, in the taxonomic journal Zootaxa. The researchers propose the common name Arabian slender catshark.

The new species has been recorded from deep waters off Kerala and the Wadge Bank region, where specimens were collected at depths ranging from approximately 400 to 600 metres. The largest known individual measured 131.5 centimetres, making the Arabian Skate a substantial member of India’s deep-sea batoid fauna.
