Great Blue Wild

The coastal waters of Mozambique are the domain of giants, from visiting humpbacks to resident whale sharks. But the tiniest species also play a big role. Brightly colored slugs known as nudibranchs inhabit shallow reefs, estuaries, and mangroves. Of the 200 species here, 90% are newly discovered. Follow the research team as they navigate fickle tides and indiscriminate fishing practices to protect the marine giants of Mozambique--and the tiny creatures that live in their shadow.
