Changing Seas

Majestic Mantas

Season 9 Episode 4 | 27m 13s

Mexico’s remote Revillagigedo Archipelago is a hotspot for oceanic mantas. Scientists are studying the local population using photo ID techniques and acoustic tags which track the movements of these mysterious fish. They are also conducting experiments to see if the filter-feeding rays are impacted negatively by microplastics, tiny pieces of toxic trash that float in the ocean.
