In this sequence of Jacques Cousteau ‘The Silent World " (from min. 50:05 to 58:07 approximately), the Calypso follows a herd of sperm whales and fatally hit a small breeding. Soon, many sharks congregate around the body and begin to devour it. The sailors are horrified and fascinated. But suddenly got mad. They attack the sharks, lift them up to the deck and killing them, with axes and maces. The crew's dog seems to not support the slaughter of sharks and goes away, or is only afraid ...? The sailors finally calm down and play curiously with barnacles accompanying sharks. Colin Dayan begins his book 'With dogs at the edge of life' narrating this sequence and observes: "... only the dog responds with what we can interpret as spot-on in Its gentle, unremitting regard".
