World-renowned shark expert Steve Backshall presents a revelatory series that reveals the secret wonders of sharks as he travels the world to dispel their reputations as cold-blooded killers. His adventures will take him from the cold depths of the planet's oceans to warm tropical shallows, following every species of shark. With populations rapidly declining all over the world, Steve Backshall hopes that shedding light on these creatures will encourage people to try and save sharks from extinction.
