Galápagos Sharks Exhibit Unusual Behavior with Manta Rays in Mexico
In Revillagigedo National Park, Mexico, researchers led by Dr. Madalena Mesquitela Pereira Cabral have observed Galápagos sharks engaging in a unique behavior with oceanic manta rays. Instead of the typical predatory interactions, these sharks were seen rubbing against the manta rays, a behavior known as chafing. This interaction, documented for the first time, involves the sharks using the manta rays as a means to remove parasites from their bodies. The study recorded both adult and juvenile sharks participating in this behavior, which may offer a more effective method for parasite removal compared to traditional cleaning stations.
