The Great White has a scary reputation, but Explorer Jacques Cousteau called the Oceanic White Tip “The most dangerous of all sharks…" Was he right?

Shark biologist Marcus Drymon unravels the mystery of the songbird-eating shark.

All across YouTube, viral videos abound of great whites and other sharks attacking boats with a ferocity and anger that has never been seen before. The question is, why? Is this simply a case of more people having cameras to video the behavior, or is something else happening? Dr. Mike Heithaus and Ph.D. candidate Sara Casareto set out to investigate what’s causing this clash between sharks and boats.

A team of experts travels to Shark Bay, Australia, to unlock the secrets of shark and dolphin combat; cutting-edge technology provides a window into this seldom-seen conflict.

Nearly 40 shark species live in the warm waters of Hawaii's volcanic islands, including white tip reef sharks, Galapagos sharks and tiger sharks.

The globe learned on December 26, 2004, that tsunamis can bring death and devastation to the world's coastlines. The product of undersea earthquakes and volcanic eruptions, tsunamis can race across oceans at more than 500 miles an hour, leaving a huge wake of destruction when they hit shore. Because it is difficult for scientists to predict how large these massive waves can be, tsunamis are one of the least understood of nature's forces, and one of the most dangerous. With insight from some of the scientific community's foremost researchers, and vivid accounts from past tsunami survivors, Tsunami: Killer Wave depicts nature at its most extreme, profiles the efforts being made to curb its effects, and illustrates the financial, physical and emotional toll it can leave on its victims.

The National Geographic Society explores the mysterious and dramatic Hindenburg explosion of May 1937 in Lakehurst, New Jersey, USA. The Hindenburg was the largest German Zeppelin that carried passengers, crew, luggage, mail, and a heavy loaf duel. Much like the Titanic, it was revered for its size as well as lavish accommodations. It had made ten round trips between Germany and the United States before its demise.
