Inspired by the spirit of adventure of early explorers like St Brendan the Navigator, Irish underwater cameraman Ken O’Sullivan voyages out into the open North Atlantic in search of the great sea monsters described in the explorers’ early texts which may well have been large whales.

Sudan was someone Zacharia Mutai spent years with, someone he knew better than his own children, someone he loved. Sudan’s death was tragic, but not a surprise. Zacharia, the head rhino caregiver at the Ol Pejeta Conservancy in northern Kenya, was caring for one of the last remaining northern white rhinos on the planet. But this is not just the story of Zacharia’s loss or of the death of a rhino. This is the story of the death of a species. A loss of such magnitude is a loss for all of humanity. Without these creatures, we suffer more than just the loss of ecosystem health. We suffer a loss of imagination, a loss of wonder, a loss of beautiful possibilities.
