About the size of a small school bus, the basking shark is the second largest fish in the ocean and is found in temperate and tropical waters across the globe. In the mid-1900s, basking sharks were observed by the thousands each year off California’s coast. Now they are rarely seen at all in this region, called the California Current Ecosystem, or CCE.

North America’s biggest marine protected area — Mexico’s Revillagigedo National Park — may have been nearly seven times smaller if not for shark-tracking data collected by researchers and alumni from the University of California, Davis.

The park, known as the “Galapagos of North America,” protects more than 57,000 square miles around the Revillagigedo Archipelago, a UNESCO World Heritage site composed of a string of four volcanic islands about 300 miles southwest of the Baja Peninsula.

However, the study found that reef fish are willing to move past that fear. They will stray far from their sheltered coral refuge and risk the possibility of being eaten by sharks and other predators if the pay-off in tasty algae is higher.
