Satellite tracking data show that giant oceanic mantas tagged in Revillagigedo National Park undertake extensive movements beyond the park's boundaries, following key migratory corridors — or migravías — that connect the protected area with international waters, the French Exclusive Economic Zone around Clipperton Island, and important Mexican marine regions such as the Gulf of California and the coastal zones of the mainland. Upon leaving the safety of the marine protected area (MPA), these mantas frequently enter regions characterized by intense fishing activity, significantly increasing their risk of interaction with fisheries and bycatch. The identification of these migratory corridors highlights the urgent need to implement collaborative, cross-jurisdictional management measures and conservation strategies to protect these critical movement routes and effectively safeguard this highly mobile and vulnerable species.
