Travelling across six continents, Steve searches through trees, deserts, swamps and seas in his bid to find his deadly 60. Animal or human – no one is safe.

As he travels across South Africa, Australia, India, Malaysia, Europe, United Kingdom, South America and North America, he encounters a host of animals with a wide variety of appearances.

Take the hippopotamus – this friendly looking animal kills more humans than anything else in South Africa. Despite its stocky shape and short legs, the hippopotamus can easily outrun a human. Having previously been timed at 30mph – it is a surprising predator that may well catch you off your guard.

What about the cuttlefish? Despite the name, cuttlefish belong to the mollusc group, and recent studies have shown that they are among the most intelligent invertebrate species. They possess 3 hearts, and their blood has a blue-green tinge. They can also change colour, with their skin flashing a fast-changing pattern, which not only acts as a method of communication, but also enables them to camouflage themselves, so that they are able to sneak up on their prey.

From smaller predators such as red back spiders and giant venomous centepedes, to larger specimens, including salt water crocodiles and great white sharks; Steve’s journey proves that when it comes to the battle for survival, size is of no importance.
