Huge Sharks Attack Submarine While Fighting Over Whale Carcass on ‘Blue Planet II’

In this crazy behind-the-scenes clip from the first episode of BBC’s new nature documentary series, Blue Planet II, a film crew encounters some aggressive bluntnose sixgill sharks (aka cow sharks) while filming a whale carcass 750 meters below the sea. Blue Planet II airs in the U.S. on BBC America in early 2018.

“The Blue Planet II team dive to over 700 meters to see what happens to a whale carcass on the seabed. Whilst filming sharks as they feast, the sharks start to take a worrying interest in the submarine!”
