What an amazing presentation that combines ocean currents, poo, and Western colonialism up to the present. All in less than 12 minutes. Incredible presenter. She knows what she's doing.

The Greenland shark is probably a scavenger feeder. As well as the largest marlin ever landed on rod and reel was caught in the Humboldt current - Not any more I would guess...
