Hawaii

Steve Backshall's pole-to-pole expedition has arrived in the remote island chain of Hawaii. Steve's adventure begins at sea, and after days of searching the open ocean he is rewarded with a thrilling view of a shark with a fearsome reputation, the oceanic white tip. After sundown, Steve dives back into the inky black, seeking out a creature often known as the sea devil. At this time of year humpbacks surround Hawaii, and Steve gets a chance to swim alongside the heavyweight males as they battle it out to win a female. On land, the team find a lightning-quick carnivorous caterpillar before exploring the volcanic lava flows created by Hawaii's mightiest force of nature.
