Manta Rays: Pandas of the Sea - Andrea Marshall

National Geographic Emerging Explorer Andrea Marshall lives just feet from the beach in Mozambique where she dives every day to study manta rays. Living in Paradise would seem to be perfect, but Marshall says the smallest amounts of human pressure can demolish a vulnerable animal. A small local fishery has reduced the manta ray population by 88% in recent years, and she's dedicated to rehabbing the numbers of these "pandas of the sea."
