Shark Vs. Whale

Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young. They walk, marching day and night in single file 70 miles into the darkest, driest and coldest continent on Earth. This amazing, true-life tale is touched with humour and alive with thrills. Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!

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.

An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.
