Where the Bay Becomes the Sea
Excerpt  (3:34) 1985, production : John Brett
The film
Tidal ecosystems are unique environments where the connections between the living and non-living features are essential for their cyclic nature. The connections between living creatures are also important as seen in this excerpt, where some species rely on a single food source such as the right whale (a protected species) that feeds exclusively on microscopic plankton called copepods.

The richness, complexity and fragility of marine life unfold like a Persian carpet in this beautiful film. The bay of the title is the Bay of Fundy, and where it meets the sea a unique ecosystem has developed. The film traces the intricate interrelationships within the food chain, from tiny plankton, through birds and seals, and finally to whales and humans. More than just a visual feast, the film is a plea for careful management of our ocean resources. First telecast as part of the Nature of Things series.
