Episode 602: Biggest Fish in the Sea

Each summer, the world’s largest known aggregation of whale sharks occurs just off the coast of Cancun, Mexico. Hundreds of these gentle giants come to the area to feed on plankton, giving experts the opportunity to learn more about the largest fish in the sea. Despite their enormous size, still relatively little is known about the animals. Scientists from the Georgia Aquarium, together with their partners from Blue Realm, tag the animals to learn more about their movements. The experts also want to protect the animals from ship strikes while they are feeding at the ocean surface, so they have installed a special device that can monitor ship traffic in the area. They plan to correlate that information with data they have collected on the whereabouts of the animals, to make recommendations for safer shipping lanes in the future.
