The carcasses of three Olive Ridley turtles were found washed ashore near Bommayarpalayam on Sunday.
A group of youth were on their daily morning walk on the beach when they spotted the carcasses of the turtles on the stretch between Bommayarpalayam and Pillaichavadi coasts.
A Forest Department official said that one of the turtles had cuts on its flippers and the carapace. The cause of death is yet to be ascertained. A post-mortem will be conducted and the carcasses will be buried on the shore, he said.
The nesting season of Olive Ridleys listed under Schedule I of the Wildlife Protection Act, 1972, is from January to March and the turtles could have arrived to the shore to lay eggs.
