North See - Nature Untamed S01 E02 Seabed

Discover the diversity of life on or near the bottom of the North Sea. These so called benthic species use special and spectacular tactics to survive. They dig, plane, drill, graze and filter. Most animals do this by touch. Immerse yourself in the world of shellfish, crabs, benthic fish, shrimp and graceful worms. What happens to dead animals and fish faeces when they drift down on the bottom?
