Bermuda Triangle: The Deadly Secrets

Follow astronaut Scott Kelly's 12-month mission on the International Space Station, from launch to landing, as NASA charts the effects of long-duration spaceflight by comparing him to his identical twin on Earth, astronaut Mark Kelly.

Earthquakes, tsunamis, volcanic eruptions, and extreme weather. Has Earth always been this way? Featuring footage of top geologic hot spots on every continent, the film traces the scientifically-based story of the 4.5 billion-year-old Earth, from the core to the crust and up into the atmosphere.

Professor Alice Roberts joins entomologist Tim Cockerill in a house filled with hundreds of spiders in a one-off documentary revealing the secret life of the spider in the home.

Join barefoot scientist Jesús Rivas in the murky marshes of Venezuela on his quest to understand these huge, fearsome reptiles. Up to 30 feet long, weighing many times more than the scientists studying them, anacondas are difficult subjects at best, but the National Geographic team captures brilliant footage of them swimming, resting, mating, and hunting prey.

Do they really launch themselves onto the shore to grab a hapless snack? See for yourself, and gain a vivid appreciation for their appetites and skills. While your jaw drops at their fearsome agility, you’ll also be learning about their migratory and other behaviours from scientists who observe them daily and strive to increase our understanding of their needs for survival. In this National Geographic ‘Wildlife Special’ you’ll journey around the globe to see their extraordinary hunting techniques in action.

Any unlucky carcass is dispatched in a matter of minutes by a feeding frenzy that attracts jackals and hyenas along with vultures. Scavenging insects swarm over the remaining bones and horns. While this film focuses primarily on the griffin vulture (“nature’s undertaker”), it considers the role of all scavengers in this harsh ecosystem. Generally despised as harbingers of death, they actually help maintain the health of the savannah by disposing of waste and returning nutrients to the soil.

Eerie, forbidding, and darkly beautiful - Okefenokee is ruled by a relative of the dinosaur: the fearsome alligator. Day and night the alligator glides silently through its steamy realm, stony eyes just above the waterline, mouth held in a seemingly perpetual smile.

The eight lionesses soon give birth to their new leaders’ cubs and there are young everywhere, feeding, playing and training for survival. But danger lurks behind virtually every bush, whether from ever-present hyenas or from a clever mongoose. One lonely cub, born late and orphaned early, endures hardships so heart-rending the filmmakers were tempted to intervene. But they decided to let nature run its unpredictable course.

An in-depth look into the isolated sport of Motocross in the much more isolated island of Bermuda.

Chris Packham presents, mentioning others that didn't quite make the list, his favorite top ten animal - and plant species from the half million discovered in the first decade of the 21st century. The animals include the most endangered African monkey, a lemur (Madagascar simian), a mouse-size and -resembling relative of the elephant, a Caribean island-adapted sloth, a shark which 'walks coral reefs on an arm', the largest mega-stick, a deep sea jellyfish without tentacles and a jungle gecko mutation happening in Malaysian state Perlis in order to flee serpent predation into caves. Plant species include a giant Venus-flytrap on Palawan (Philipines) and the largest ever orchid from Peru.
