A large amount of volcanic stones known as pumice stone were found in the body of a young sea turtle that had been rescued on the Okinawa coast, according to a spokesperson for the Okinawa Churashima Foundation on November 13.
The foundation believes the turtle accidentally ate the pumice stones that drift from the August eruption of the Fukutoku-Okanoba submarine volcano in the Ogasawara Islands.
The cause of the death of the endangered green turtle is still unknown. He was found in a weakened condition on a sandy beach near the town of Chatan in Okinawa on November 11 and was taken to the Churaumi Aquarium in Okinawa. He died the next day.
A computed tomography (CT) scan confirmed that there were large amounts of pumice stone in her intestines. The turtle, whose shell was 6.5 cm long, was reportedly born during the summer.
According to Isao Kawazu, Ph.D. who focuses on the reproductive biology and ecology of sea turtles at the Okinawa Churashima Foundation Research Center, “Because it was a small turtle, it may not have not been able to remove the stones from his intestinal tract. “
Pumice stone believed to have come from the eruption has been found in various parts of Okinawa and Kagoshima Prefectures, as well as in Shikinejima (Niijima village), one of the smaller Izu Islands in Tokyo Prefecture, and more recently along other parts of the Japanese Pacific. littoral.
