Dolphins: The Wild Side follows these mammals in the wild as they fight for mating rights, hunt for food, and clash with other dolphin species. Thanks to some brilliant underwater camerawork, we're treated to the sight of dolphins hydroplaning through 10 inches of water after fish, ramming one other in a quarrel over females, and evading a group of hungry orcas in Alaska. (Killer whales are actually part of the dolphin family, but they feel no compunction about feeding on their smaller cousins--not a scene for the squeamish!) But perhaps the most impressive part of this documentary are the scenes of a dolphin pod working in concert to trap a shimmering, mammoth school of sardines. Through calculated use of air bubbles, tail slaps, and sonic pips, the animals corral their prey and have a feast. The clever, and at times ruthless, nature of these mammals is on abundant display in this entertaining documentary

NATIONAL GEOGRAPHIC begleitet ein Team von deutschen und US-amerikanischen Tauchern bei der Erforschung der legendären „Blue Holes" der Bahama-Inseln, kreisrunde, nach oben offene Unterwasserhöhlen, die bis zu 200 Meter tief sind. Da es am Grunde dieser Schächte keinen nennenswerten Wasseraustausch gibt, tummeln sich hier nur besonders widerstandsfähige Einzeller - doch es finden sich auch Fossilien aus längst vergangenen Erdepochen. Vielfach lagen die jetzt überfluteten Höhlensysteme noch vor wenigen tausend Jahren oberhalb des Meeresspiegels, und so haben sich hier auch die Überreste zahlreicher Tiere und sogar von Menschen erhalten. Unterwasserfilmer Wes Skiles beobachtet das Taucherteam bei seinen aufregenden Expeditionen in die Tiefe und liefert spektakuläre Bilder aus einer bislang nahezu unzugänglichen Welt.

In 1995, the first gray wolves were transported from Alberta, Canada to Yellowstone National Park, to repopulate the sprawling landscape with the species, absent for more than 70 years. The following year, a second wave of wolves was brought to the park from British Columbia, Canada; five of them were released together, and they were named the Druid Peak pack. Since the arrival of those first immigrants, wolves have thrived in Yellowstone — and none more dramatically than the Druids. The epic history of the Druids, one of more than a dozen packs now occupying the 2.2 million acres of Yellowstone, is documented in NATURE’s In the Valley of the Wolves, was produced and shot in High Definition by Emmy-award winning filmmaker Bob Landis.
