Where Do These Ocean Giants Disappear To North Atlantic The Dark Ocean 4K UHD BBC Earth_360P

Basking sharks can grow to be up to 10 metres long and can weigh up to 5 tonnes. Despite their massive size, they are only ever seen for a few weeks per year, when they feed on plankton in the sunny waters during the spring months. Which begs the question, where do they go for the rest of the year?

Inspired by the Irish ancestors that ventured before him, underwater cameraman Ken O’Sullivan explores the dark depths of the North Atlantic – and immerses the viewer in the mesmerising world of marine life exploration. He addresses the urgent struggle to conserve the stunning sea life he encounters and pays homage to the ancient spirit of exploration.
