Some of the waters these whales traverse are very cold – too cold for most humans – but not for renowned endurance swimmer, Lewis Pugh, who set the world record for most southerly swim. He swam 350m [1,150ft] in the Bay of Whales in Antarctica’s Ross Sea, where the water temperature was -1C [30F] and air temperature of -37C [-34.5F]. A feat all the more remarkable because he did it in only a pair of trunks, cap and googles.
