Context: As a record number of 4.92 lakh Olive Ridley turtles have crawled to the Rushikulya coast in Odisha, scientists have tagged more than 6,000 turtles to gather more information about their breeding behaviour and migration.
This is the highest nesting which has broken all records for the coast.
Before the tagging of the turtles, it was assumed that it was a migratory species.
Now the tagging has revealed that the Olive Ridley turtles can travel up to Sri Lanka.
Also, the migratory turtle is present in the entire Bay of Bengal and even on the coast of Andhra Pradesh and Tamil Nadu.
