East-west journey of satellite-tagged turtle Dhaval Laxmi suggests Maharashtra’s coast may host Olive Ridley turtles from wider Arabian Sea populations that anticipated earlier

Rescued from fishing nets off the Maharashtra coast and later satellite-tagged, an Olive Ridley sea turtle has surprised scientists by swimming across the Arabian Sea to near Masirah Island off Oman, revealing an unexpected migration route. Tracked by the Wildlife Institute of India in collaboration with the Mangrove Foundation and the Dahanu Forest Division, the turtle — named Dhaval Laxmi — defied earlier patterns that showed southward coastal movement. Scientists say the east-west journey suggests Maharashtra’s turtles may belong to wider Arabian Sea populations.
Why this journey matters
First satellite-tracked Olive Ridley from Maharashtra to move east-west across the Arabian Sea
Challenges: Earlier data showing southward coastal migration
. Indicates turtles along Maharashtra may belong to wider Arabian Sea populations
What scientists say
“This kind of east-west movement was not something we had expected,” said Dr Suresh Kumar, senior scientist, Wildlife Institute of India
. The turtle may be returning to its original foraging or nesting grounds
. Olive Ridleys may nest at multiple locations across years
Official view
“Continued tracking will provide valuable insights into population distribution, movement patterns, feeding areas and behaviour,” said SV Ramarao, additional principal chief conservator of forest (APCCF) and head, Mangrove Cell
Current location
As of February 22, Dhaval Laxmi was tracked 190 km southeast of Masirah Island, off the coast of Oman
