Study Reveals Olive Ridley Turtles in Indian Ocean Are Among World’s Oldest
A study by WII and CCMB indicates that Olive Ridley turtles in the Indian Ocean represent the oldest populations globally, highlighting significant nesting activity in Odisha. The research reveals distinctions in genetics and nesting behavior compared to other populations and emphasizes the impact of climate change on sex ratios among hatchlings.
A recent study by the Wildlife Institute of India (WII) and the Centre for Cellular and Molecular Biology has revealed that the Olive Ridley turtle population in the Indian Ocean is among the oldest globally. This study also highlights that the nesting behavior observed in Odisha shows genetic distinctions from Olive Ridley populations elsewhere, including South America. The research was published by the Indian Institute of Science and DakShin Foundation, concluding a 16-year monitoring project.
The Olive Ridley turtles, recognized as the smallest marine turtles, typically nest at the Rushikulya and Gahirmatha beaches in Odisha. Last month, an exceptional event was recorded when over 1.3 million Olive Ridley turtles laid eggs at these locations, breaking the previous record of 1.15 million set in 2023. Rushikulya, located in the Ganjam district, ranks among the largest nesting sites worldwide.
The study provides significant insights into the evolutionary history and current status of Olive Ridley turtles in the Indian Ocean. It establishes the eastern coast of India as a key location for understanding the species’ ancient populations and emphasizes the impact of climate change on their reproductive dynamics. Continuous monitoring is vital for comprehending their breeding and nesting behaviors as global conditions evolve.
