Galapagos sharks have discovered an innovative way to scratch their itches by using manta rays as giant scratching posts. Observed at dive sites near Mexico’s Revillagigedo archipelago, these sharks rub their snouts and gills—areas prone to sea lice—against the rough skin of manta rays. While juvenile sharks are tolerated by the mantas, adult sharks cause the rays to try to escape. This behavior is not aggressive but rather a clever solution to a parasite problem, as cleaning stations where fish remove parasites can become crowded. This unique interaction highlights the sharks’ adaptability and problem-solving skills. Scientists believe this behavior might have been inspired by smaller fish using sharks in a similar way, showcasing the trial-and-error nature of shark behavior.
