Wildes Deutschland: Unbekannte Tiefen

Germany’s underwater world is a well-kept secret. Hidden beneath the surface are some little-known creatures, from strange moss animals to massive prehistoric fish. This is a journey through Germany’s rivers, streams and lakes, from the snow-clad peaks of the Alps to the tidal waters of the North Sea.  We meet powerful hunters like the pike and sinister meat-eating plants like the bladderwort. It’s journey unlike any other, offering a rare glimpse into a colourful and mysterious world. (ZDF)
