This National Geographic documentary explores one of the world's few remaining tidal mangrove forests, located on the small island Siarau off the coast of Borneo. This forest is flooded everyday with the incoming tide, which has caused both animals and plants to adapt in unusual ways. Particular oddities -- such as lung fish who can live out of the water and trees with root systems above ground -- are revealed and explained with high-quality photography and thorough scientific reasoning.
