Great Blue Wild

The 1,600-mile coast of Mozambique is a magnet for the world's largest marine dwellers, from manta and sting rays to sharks and dolphins. While manta ray numbers are impacted by a migration path that overlaps with their predators, the biggest threat comes from bad fishing practices. Join marine specialists Andrea and Nakia as they set out to identify the favored habitats of manta rays, learn about their migratory habits, and devise strategies to protect the species from catastrophic decline.
