An underwater camera reveals a rarely seen moment when a tangled whale swims free.
As part of its "Big Blue Live" series, BBC posted a YouTube video of a rescue mission, in which a tangled humpback whale is freed from 300 feet of rope from a crab pot.
The team of rescuers, authorized by the National Oceanic and Atmospheric Administration, tracked the whale for 600 miles in order to untangle him. Luckily for us, a camera was nearby to capture an up-close view.
First, the team inspected the whale's tangled tail.
