This Project

Turtle Island Restoration Network mobilizes people to restore oceans, preserve rivers and streams, and protect the marine wildlife that call these blue-green waters home. A shark-related fatality in Isla Del Coco in Costa Rica in November 2017 has drawn attention to tiger sharks in the region. This project utilizes non-invasive research techniques to understand tiger shark feeding behaviors and identify population sizes. The goal of this project is to identify tiger sharks and create protocols for protecting both tiger sharks and island tourism.
