With Pete Smith providing dry off-screen commentary, we watch some serious fishing: a marlin caught near Catalina, a hammerhead shark caught then wrestled in a small rowboat near Baja, the largest (721 pounds) great white shark caught to date in California waters, Chinook Indians catching salmon at Celilo Falls in Oregon - each with his designated place on the river where his ancestors stood, and, last, a crew on a boat off Mexico hoisting and hurling tuna using unbarbed hooks (baited only with a feather) as fast as they can as long as the school is there - backbreaking work - but a $25,000 catch.

The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth. Hiding in the vast rivers and streams is an electric grid, a bizarre community of fish with a highly sophisticated electric sixth sense. Using electricity, these "Super" fish can communicate wirelessly, control each other remotely and emit shocks that can stop a human heart. This cryptic world has mystified scientists throughout the ages. Now an intrepid scientist, Will Crampton ventures back into the dark jungles where the inspiration for our technology driven world first emerged, in an attempt to unravel their secrets and unlock the electric code.

Down Under, just a few nights after the November full moon - when water temperature and tides are just right - one of nature's most extraordinary events explodes into life. Thousands of coral join in an elaborate mating ritual, a synchronized dance of naturally occurring phenomena that help increase the coral's odds of survival. Journey through more than 1,200 miles of Australia's treasured Great Barrier Reef to discover the secrets of the unique marine life that inhabit this dazzling spectacle, considered to be the world's biggest single structure made by living organisms and declared a World Heritage Site by UNESCO.

A 3-D documentary chronicling a sea turtle's journey across the oceans.

An ecological drama/documentary, filmed throughout the globe. Part thriller, part meditation on the vanishing wonders of the sub-aquatic world.

Examines the devastating effect that overfishing has had on the world's fish populations and argues that drastic action must be taken to reverse these trends. Examines the imminent extinction of bluefin tuna, brought on by increasing western demand for sushi; the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation.

Narrated by Academy Award winners Sissy Spacek and Herbie Hancock, River of Gold is the disturbing account of a clandestine journey into Peru's Amazon rainforest to uncover the savage unraveling of pristine jungle. What will be the fate of this critical region of priceless biodiversity as these extraordinarily beautiful forests are turned into a hellish wasteland?

The Indonesian archipelago in the Indo-Pacific Ocean comprises thousands of islands, atolls and the largest concentration of coral reefs in the world. This rich and varied environment is a product of a unique set of natural circumstances. The equatorial sun powers ocean currents among the tiny dots of land. Where the archipelago meets the western tip of New Guinea an intersection of ocean currects creates perhaps the world's richest reefs - in the region of the Rajah Ampat Islands. A coral reef houses a myriad of colors, shapes and patterns: from the bulb tentacle anemone which protects, and in turn is protected by, the brightly coloured clownfish; to the multi-branched gorgonian, home of the tiny pygmy seahorses.

The story of South Africa’s sardine run is brought vividly to life on camera.

The Hawai'ian Islands are ground zero for the aquarium trade who capture and traffic reef fish for hobbyists’ tanks, decimating the reef, ocean and earth’s oxygen. Native Hawai'ians, conservationists, scientists, aquarium fish collectors and breeders are locked in a controversy over the stunning “treasure of Hawai'i” – the ornamental fish.

Riefenstahl explores the undersea world of coral reefs in various oceans around the world. Soundtrack by Giorgio Moroder.

Ungezähmt - Im Fluss des Lebens

The three-spined stickleback is shown. Nest building, zigzag dance, fanning at the nest, sometimes following a female, also short mouth fights, the female swimming into the nest, spawning, the male poking at the rear end of the partner, inseminating the eggs in the nest after the female swims away.

Ten thousand years ago, native people painted pictures of white sturgeon on the rocks near where they lived. These impressive fish, the largest and one of the oldest in North America, were an important part of the tribe's diet and the inspiration for their elegant sturgeon-nosed canoes. But over the past 200 years dikes and dams have changed the river so much that the sturgeon no longer successfully reproduce. Now, the people whose culture is bound up with these fish and the people who control the flow of the river today are working together to restore the Kootenai River White Sturgeon to their ancestral home.

How did your body become the complicated, quirky, amazing machine it is today? Anatomist Neil Shubin uncovers the answers in this 3-part science series that looks at human evolution. Using fossils, embryos and genes, he reveals how our bodies are the legacy of ancient fish, reptiles and primates — the ancestors you never knew were in your family tree.

Rick Rosenthal goes on a quest that plumbs the secrets of the legendary bluefin tuna. This fish can weigh up to 1,500 pounds and can move up to 50 miles per hour. Here he catches a bluefin tuna on camera.
