Steve Backshall continues his search for the planet's deadliest predators with a visit to Florida in the USA.

He dives into the crystal clear waters of the Silver Springs river to swim with a wild alligator, before wading into a swamp to try and catch a slippery amphibian, the weird and wonderful amphiuma. Steve then heads to the drier pine woodlands on the trail of America's largest serpent, the eastern diamondback rattlesnake.

Steve then travels to South Carolina, joining a team of scientists, tracking and tagging wild bobcats. His journey ends back in the water, in the Florida Keys where he witnesses first-hand the sophisticated hunting methods of a highly intelligent predator, the bottlenose dolphin. Show less
