Otters are so proficient at capturing the fish they live on, that they have lots of time left over for play. And they seem to play with reckless abandon, sliding down steep canyons in deep snow, swimming under the ice in Yellowstone Lake. They submerge us into the lake to find strange underwater spires only recently discovered by man. Other creatures sometimes survive bitter winter seasons by stealing fish from the otter. Actually, they're pretty good at defending themselves, and this program catches some astonishing action between them, coyotes, eagles, beaver, even an occasional grizzly bear.

By the end of the Ice Age - only ten thousand years ago - many great mammals had died out. The woolly mammoth, the dire wolf, the saber-tooth cat and others disappeared as a result of severe climatic changes that engulfed the planet. And yet other animals persevered. Today, they go on in dwindling numbers as the last of the Ice Age survivors. Scientists are piecing together their past while others work to safeguard the future of these living relics. Despite climate changes over the past 15,000 years and human predation, their descendants persist in a few unspoiled regions of the globe.

How the Cichlid survived and evolved is an incredible story for, millions of years later, there are over 200 new species - all found only in Lake Tanganyika. Incredibly, they have evolved to look like coral reef fish. There are cichlid equivalents of tuna, snapper, gobies and goatfish.
