Killer Shark vs. Killer Whale examined an extraordinary incident that occurred at the Farallon Islands, 27 miles off San Francisco, in October 1997.

What is happening between the two apex predators of the oceans? There are still so many questions left to answer.

There’s a buzz along the California coast. The waters are teaming with great white sharks. Nearly every day there are reports of beachgoers, kayakers and swimmers having close encounters.

Or does data tell a different story? In Counting Jaws, researcher Dr. Mike Domeier attempts to unravel this mystery.

In this enhanced episode, we assemble a team of leading scientists and embark on a global mission to find and identify the most aggressive sharks on Earth. Discovering that females do indeed outgrow males in size, we ask the burning question: are they more deadly?

Join brother-and-sister-team Bob and Joyce Poole as they travel to Gorongosa National Park in Mozambique on a simple but dangerous (some would say crazy) mission: to confront traumatized, charging elephants; teach them not to attack people; and convince them that after 16 years of civil war, poaching and destruction, the humans in the park now come in peace and offer protection, not bloodshed and terror. Their plan is a complex mixture of science and what some might consider insanity: Bob and Joyce will drive directly into the path of charging Gorongosa elephants - and refuse to back down. The hope is to habituate the elephants to people, prove that tourists are not a threat, and hopefully, not get trampled in the process.
