COASTAL SEAS | The Living Border Between Land and the Deep Blue Sea | FULL DOCUMENTARY

Explore coastal seas, where changing tides transform feeding grounds, expose hidden prey, and reshape the daily struggle for survival. This ocean documentary reveals the marine life living between rocky shores, tropical mangroves, sandy seabeds, and underwater kelp forests. Discover how mussels and barnacles endure low tide, and meet mudskippers that remain active after the water retreats. Along exposed beaches, shorebirds search for food, while migrating red knots depend on horseshoe crab eggs to fuel their journey. As the tide returns, flooded coastal habitats offer shelter to juvenile lemon sharks. In cooler waters, giant kelp creates underwater forests, where sea otters feed on invertebrates and can influence the grazing pressure shaping the habitat below. Beyond the kelp, bat rays uncover meals hidden beneath the sand. Bottlenose dolphins use sound to locate prey, while harbor seals divide their lives between underwater feeding grounds and exposed shores where they rest and nurse their young. From a fish moving across wet mud to a seal pup entering the water, discover the adaptations that make survival possible along the ocean’s changing edge.
