As springtime dawns on the frozen landscape of Canada's high Arctic, Adam Ravetch sets off in search of one of the region's most massive and misunderstood animals - the walrus. Known as Man " The Walrus Man" Ravetch has devoted much of his career to documenting the lives of these tusked giants. Ravetch is on a mission to capture on film the drama when polar bears and walruses meet face-to-face. He also captures the unique and rarely seen behaviours of mother walruses and their newborn calves. At first glance, the eastern Canadian Arctic seems to be a place of frozen desolation. But, here amidst the ice floes, walruses live an arctic existence, battling with the elements and against predators for survival. Weighing up to two tons, walruses paint a familiar picture with their characteristic tusks and bristly moustaches. But amazingly, much about these animals remains a mystery. It is Ravetch's goal to unlock the secrets of these unique creatures. In Battle of the Arctic Giants Ravetch captures what is believed to be the first underwater footage of a female walrus as she nurses and protects her newborn calf. And, he also films a polar bear rushing into a walrus herd and killing a calf, even facing down the calf's huge, tusk wielding mother as she tries in vain to thwart the attack. From the tender to the terrifying, scenes like these illustrate the extreme contrasts in this rugged landscape. On an epic journey that takes him onto drifting ice floes, diving into sub-zero waters and camping alone on a tiny island with hungry polar bears as neighbours, Ravetch captures the drama of walruses' real-life struggles as spring turns to summer in the frozen Arctic.

A single swarm of killer bees can deploy an attack force of 80,000 stingers, chase predators for a quarter of a mile, and bring down a creature as large as a horse. Killer bees have pushed farther north than many scientists thought possible and are now colonizing in the southern United States. Can scientists, beekeepers, and exterminators stop the invading hordes?

Anyone who has ever worked in a controlled environment like a zoo with venomous snakes knows that the possibility of a venomous snake bite is serious business. Protocol including alarms and lock down procedures are common place. The right snake, the wrong timing and fangs meeting flesh merits an emergency situation and the entire facility jumps into action. Yet, there are individuals who keep deadly snakes in situations without any backup. Are they thrill-seekers or just naive? Henry Rollins meets people obsessed with dangerous snakes in
