Video Description
Watch as the tidal seas explode with life – thanks to the ever-present tug of the moon's gravity – and learn why tidal marshes are one of the most ecologically productive parts of the world. Broadcast 24 October 2001, the penultimate episode deals with marine life that is structured around the rising and falling tides. These are caused by the gravitational pull of the orbiting moon, but in some locations, this can also combine with the power of the sun to create a tidal bore. The world's largest tides are to be found in the Bay of Fundy in Nova Scotia and therefore it is a rich feeding ground. A school of finback whales is closely shadowed by a flock of Cory's shearwaters. However, they only have a limited time to feed before low tide, when they must retreat and other creatures appear. Elsewhere, some of the latter include sand bubbler crabs, bears (which feed on shellfish) and a snail species that can 'surf'. The extreme spring tides allow opportunists to forage further, and racoons are shown tackling a red rock crab. Some larger fish that hunt on the seabed, such as nurse sharks and stingrays, are forced to sit and wait until there is sufficient water in which to swim. A giant horse conch is shown devouring a tulip snail, and hermit crabs battle over its vacant shell. The varying water levels are no obstacle to tarpon: they can breathe air. This enables them to inhabit stagnant areas and hunt in them. The autumn equinox combines with a hurricane off the Bahamas to create a much higher tide than is usual, flooding large parts of the coast. When the sea recedes, it leaves behind salt: food for brine shrimps and the perfect habitat in which flamingos can breed.

Frozen Seas
Animals living in and out of the water face their greatest challenge in the crippling polar winters. Breathtaking, rare footage shows how animals survive in these hostile environments.
Coral Seas
A coral reef is one of the most stunning sights on earth; a riot of color, teeming with fish. But this seeming tropical paradise is a Darwinian battleground where every species is locked in a daily life and death struggle, including the coral itself.
Open Ocean
Venture into the largest section of open ocean in the world, where endless blue stretches in every direction. This blue wilderness can seem like an empty desert, but here the ocean's fiercest, fastest and most ruthless predators stalk their prey over immense distances.
The Deep
Two-thirds of the earth is covered in water, but we've only explored about one percent of the ocean floor. With the help of space-age submersibles, take a spectacular journey to previously unreachable depths.
Tidal Seas
Watch as the tidal seas explode with life – thanks to the ever-present tug of the moon's gravity – and learn why tidal marshes are one of the most ecologically productive parts of the world.
Coasts
The boundary between land and sea serves as a demarcation line between the beach-loving creatures that live onshore and the hungry predators that wait just beneath the surface of the water.
Seasonal Seas
Shafts of sunlight radiate through the ocean's 'ceiling' and provide energy for the myriad creatures that live in the temperate sea, the richest of all underwater habitats.
Ocean World
The oceans are an integral part of the Earth's life cycle, influencing weather systems and supporting an enormous range of life. Explore the sheer scale, power and complexity of the mysterious oceans that govern our blue planet.
Bonus Feature
Interviews with the filmmakers and scientists, including, Doug Allan, Rick Rosenthal, Dr. Martha Holmes, and Mike deGruy
Editorial Review from Amazon.com
Extraordinary footage and eloquent narration by David Attenborough highlight the BBC's remarkable wildlife series The Blue Planet: Seas of Life. "Ocean World" begins with astonishing views of a gigantic blue whale--the elusive Holy Grail of undersea photography--and the marvels continue to demonstrate the power, diversity, and profound ecological influence of Earth's oceans. "Frozen Seas" examines whales, walruses, penguins, and other creatures under the extreme conditions of the Arctic and Antarctic Circles. The next two episodes are even better. "Open Ocean" travels thousands of miles into the vast "liquid desert," where currents determine how the ocean's diverse life forms will assume their places in the food chain. More amazing, "The Deep" descends with a state-of-the-art submersible to the ocean's abyssal plain and beyond, filming such bizarre creatures as the fangtooth, bioluminescent jellies, transparent squid, the giant-mouthed gulper eel, and the never-before-seen hairy angler fish.
"Seasonal Seas" focuses on the explosion of life that accompanies every annual blooming of plankton, numbering in the countless billions and captured here with brilliant microphotography. In "Coral Seas," miles-long reefs of living coral are explored, from deep within (requiring brief computer animation) to the surrounding environs, where you'll see white-tipped sharks in a feeding frenzy while beautiful harlequin shrimp wrestle with a starfish. "Tidal Seas" explores the myriad life forms that thrive when lunar gravity pulls the oceans offshore. "Coasts" is easily the most brutal episode, but no less mesmerizing. The most unexpected, and horrifying, sequence is the orca, earning its "killer whale" nickname by capturing, killing, and tail-tossing a seal pup--a sequence so mysteriously primal that even the most seasoned marine biologist will be utterly amazed. One of the finest wildlife programs you're ever likely to see, The Blue Planet: Seas of Life provides the privilege of visiting a truly alien world teeming with the rarest wonders of nature. The series was recut into the feature-length Deep Blue in 2005. --Jeff Shannon
