Philippine police said Friday they had seized 70 dead hawksbill marine turtles, a critically endangered species illegally trafficked for its prized shell, and arrested two suspects. Hawksbills face an extremely high risk of extinction according to Swiss-based International Union for Conservation of Nature as their shell is used for making jewellery and hair ornaments. Two local men were arrested Thursday while transporting the dead hawksbills by boat off the coast of Dumaran town on Palawan island, police chief Arnel Bagona told AFP.
