The environmental ministry says it is seeking trade restrictions on the hammerhead shark.
The ministry said that it has provided the appropriate documentation to the Convention on International Trade in Endangered Species of Wild Fauna and Flora, known as CITES. The inclusion will take effect Sept. 25, said the Ministerio de Ambiente y Energía.
The listing calls upon other countries to help protect the species. The listing will impose restrictions on shark finners who transport fins of the sea creatures in and out of Costa Rica.
The hammerhead is the signature predator in the vicinity of the Isla del Coco, and there are many hundreds of the shark living in protected waters there.
