In Mexico, Steve Backshall takes to the water in search of a monster of the deep seas.

Steve Backshall and his long-suffering crew return for a brand-new series of deadly encounters with animals hoping to earn a place on his hallowed Deadly 60 list. Steve and crew pitch up in British Columbia, Canada. It is an explorer's paradise with infinite untouched wilderness and spectacular animals, but it's the creatures of the deep that Steve is on a mission to find. In the giant underwater kelp forests lurks a swimming giant, the wolf eel. It is a monster that strikes fear into some of the world's spiniest creatures, biting clean through their defensive spikes with ferocious chisel-like teeth and strong powerful jaws - not surprising when you consider its head is the size of a football. Steve then finds a trail of discarded crab shells which leads him onto his next deadly encounter, this time with 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. Given they can have an armspan as big as a truck, as a crab killer it is without equal. Then Steve is off in search of what could arguably be the most deadly animal in the world. They are referred to as wolves of the water, not only because of a mouthful of killer teeth but because they hunt in packs - it's the orca, otherwise known as killer whales. They are one of the most awesome predators on the planet - they have it all - size, speed and power and when Steve goes kayaking in amongst them he gets the surprise of his life when they start breaching all around him.
