Shark Island

Steve Backshall continues his expedition from the Arctic Circle to Antarctica by doing something quite extraordinary - swimming outside of the cage with the most feared shark on the planet, the great white.

Steve and the team travel to Guadalupe Island. One hundred and fifty miles off the Mexican coast its waters are a hotspot for these huge sharks. Diving into the crystal clear sea, Steve discovers what attracts great whites to this remote rock - their prey, Guadalupe fur seals. These underwater acrobats swim rings round Steve but even their speed and agility is no match for the great white.

Back on the boat it is time for the main event as a huge great white shark is circling. Stepping out into the blue abyss, Steve's heart is racing as he swims alongside a feared top predator. It's a truly Deadly encounter he will never forget.
