Taningia silasii: New Deep-Sea Octopus Squid Species

Introduction: Taningia silasii is a deep-sea squid identified by researchers at the ICAR–Central Marine Fisheries Research Institute (CMFRI), Kochi, highlighting India's contribution to marine taxonomy and deep-sea biodiversity research.

Key pointers

  • Common name: Indian octopus squid.

  • Scientific name: Taningia silasii.

  • Discovery region: Arabian Sea, off the Kollam coast of Kerala.

  • Collection depth: Approximately 390 metres.

  • Research institution: ICAR–Central Marine Fisheries Research Institute.

  • Animal group: Mollusca, class Cephalopoda.

  • Family: Octopoteuthidae.

  • Distinctive feature: Adults of this group lack the two long tentacles typically seen in many other squids and have eight arms.

  • Scientific identification: DNA barcoding helped establish its distinction from the previously known species Taningia danae.

  • Naming significance: The species honours marine biologist E. G. Silas.

  • Scientific importance: Improves understanding of deep-sea diversity in Indian waters.

UPSC focus: Taningia silasii is a squid, not a true octopus. Both belong to the cephalopods, but they are distinct groups.
