A tagged Olive Ridley sea turtle has accomplished an extraordinary feat, traversing over 3,500 kilometres from Odisha’s Rushikulya beach all the way to Maharashtra’s Ratnagiri coast, crossing two ocean basins in a remarkable long-distance migration. The incredible journey of this turtle, identified by its tag ‘03233’, has not only astounded researchers but also provided groundbreaking insights into the species’ nesting behaviour.

The turtle was originally tagged by the Zoological Survey of India (ZSI) during the 2021-22 nesting season on the eastern coast. Its subsequent discovery nesting on the western coast represents a rare and significant migratory event. This unprecedented observation, enthusiastically shared by IAS officer Supriya Sahu on X (formerly Twitter), marks the first confirmed instance of an Olive Ridley turtle nesting on both the eastern and western shores of India.

This monumental journey has profound implications for our understanding of current turtle conservation models. The data suggests a flexibility in nesting sites previously unknown for this species, prompting a re-evaluation of established conservation strategies.

Taking to X, IAS Supriya Sahu highlighted the crucial learnings for Tamil Nadu and other coastal states:

“Mind-blowing journey of Olive Ridley ‘03233’! Swimming over 3500 km from Odisha to Maharashtra, crossing two ocean basins! This FIRST EVER confirmed nesting on both Indian coasts is HUGE for conservation. What does this mean for TN?

  • Initiate tagging programmes NOW: We need robust tagging initiatives to unravel the mysteries of long-distance turtle migration patterns.
  • Anticipate climate impacts: This new understanding of migration corridors is vital to predict and mitigate the effects of climate change on marine migration and nesting behaviours.
  • Refine conservation strategies: Migration data is crucial for updating conservation zones and enhancing marine biodiversity planning along both our eastern and western seaboards.”

This remarkable turtle has not only completed an epic swim but has also charted a new course for turtle conservation in India.
