Steve Backshall learns about sharks. Steve meets one of the ocean's greatest sharks. The oceanic whitetip is an adventurer of the abyss. Steve and his crew track down this nautical nomad in the Pacific Ocean off the coast of Hawaii. In the empty ocean, they are constantly on the move searching for food, relying on some vital features - their fins. Back in Steve's Shark Lab, he reveals how the shark uses its different fins for perfect power and sensitive steering.
