Series 2: 2. British Columbia

Steve and crew pitch up in British Columbia, Canada. It is an explorer's paradise with infinite untouched wilderness and spectacular animals, but Steve's focus is on the creatures of the deep. In the giant underwater kelp forests lurks a swimming giant - the wolf eel. This monster strikes fear into some of the world's spiniest creatures, biting clean through their defensive spikes with ferocious chisel-like teeth and powerful jaws - not a surprising achievement when you consider that its head is the size of a football.\n\nSteve then finds a trail of discarded crab shells which leads him on to his next deadly encounter - an eight-legged sea creature which can easily reach the size of a family-sized tent. Armed with a vicious biting beak, the giant Pacific octopus makes light work of a crab's shell, and Steve comes face to face with one and quite literally gets wrapped up in his encounter with it. It has an extraordinary arm span and is a crab killer without equal.\n\nThen Steve is off in search of what could arguably be the most deadly animal in the world. Called wolves of the water - not only because they have a mouthful of killer teeth but because they hunt in packs - they are orcas, otherwise known as killer whales. One of the most awesome predators on the planet, they have it all - size, speed and power. When Steve goes kayaking in amongst them, he gets the surprise of his life when they start breaching all around him.
