changing seas

The remote Revillagegdo Archipelago off Mexico's Pacific coast is a hotspot for giant mantas that interact with awe-struck scuba divers. 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.
