In this episode, Steve goes in search of Deadly Predators with the greatest super-senses on earth.

First up, Steve heads up into the canopy to get a unique view of the UK’s largest bat, the noctule bat, as he wants to witness bats echolocating first hand. He then meets human echolocator Juan, who has been blind from birth, and uses echolocation just like a bat to see his world. Steve learns all the tips and tricks to see if he can learn to echolocate and complete our Deadly obstacle course.

The mighty sperm whale creates the loudest sound on earth. Using the latest CGI, we take a trip inside a sperm whale’s huge head to discover how they achieve such an extraordinary sound and perform a demonstration with an air vortex canon to see just how powerful it really is.

Finally, Steve comes face to face with a copperhead snake. These phenomenal snakes are pit vipers, meaning they have heat-sensing pits that enables them to sense their prey in complete darkness. Steve puts the snake to the test by seeing whether it will strike a cold water balloon or a warm one. He then puts his heat sensing to the test in the weirdest game of hide and seek, as he uses a thermal imaging camera to try and track down his team in our Deadly Junkyard. Show less
