Abstract: Whale sharks (Rhincodon typus) and manta rays (Manta spp.)represent some of the most iconic species of fish worldwide and yet only recently are their patterns of movement becoming known. Whale shark and manta site fidelity and movements in relation to ephemeral food sources and a host of environmental factors are being elucidated through a long term and multi-partner project named the MarineMeganet. The Western Caribbean and Gulf of Mexico possess several aggregations of whale sharks and a large aggregation of manta rays as well as a range of other species of ocean giants that gather seasonally to feed. Although there are no targeted fisheries for the world's largest fish and ray in this region, their large and predictable aggregations remain at risk from ship strikes, uncontrolled tourism and, in the case of the whale shark, the capture of its food source (eg fish that produce the spawn that whale sharks feed on). To better understand aggregation dynamics of whale sharks and manta rays we are investigating their patterns of movement in relation to ephemeral food pulses and anthropogenic threats by deploying satellite location only tags that will provide near real time tracking information to inform the management and conservation of these species.Los tiburónes ballena (Rhincodon typus) y las manta rayas (Manta spp.) representan algunas de las especies más emblemáticas de peces en todo el mundo y sin embargo sólo recientemente sus patrones de movimiento han sido revelado. La fidelidad al sitio y los movimientos en lo referente a fuentes alimenticias efímeras y una serie de factores ambientales se están esclareciendose a través de un largo plazo y el proyecto denominado el MarineMeganet. El oeste del Caribe y el Golfo de México poseen varias agrupaciones de tiburones ballena y una gran acumulación de manta rayas, así como una variedad de otras especies de gigantes del océano que se reúnen por temporadas para alimentarse. Aunque no hay ninguna pesca regional enfocada hacia estos planktivoros grandes, sus agregaciones grandes y predecibles permanecen en riesgo de huelgas de la nave, turismo descontrolado y, en el caso del tiburón ballena, la captura de su fuente de alimento (por ejemplo los peces que producen la semilla que se alimentan de tiburones ballena).Para mejor comprender la dinámica de la agregación de tiburones ballena y de las manta rayas estamos investigando sus patrones de movimiento en relación con pulsos de alimentos efímeras y amenazas antropogénicas mediante la colocación de etiquetas satélites que proporcionarán información para la gestión y conservación de estas especies de seguimiento en tiempo casi-real. This dataset is a summarized representation of the telemetry locations aggregated per species per 1-degree cell.
