[ti:] [ar:] [al:] [00:00.51]A pod of 12 bull sperm whales has become fatally stranded. 12 [00:06.28]Was this stranding caused by one whale making a navigational error? [00:10.84]No one knows. [00:12.56]But with social bonds so strong, [00:14.69]the other whales can't help but follow. [00:18.12]One whale is still alive, [00:20.50]but without sufficient water to support his incredible bulk, [00:23.94]his internal organs will be crushed. [00:27.08]Left like this, he will die within days. [00:31.43]Thankfully, our attitude to sperm whales [00:33.66]has changed from exploitation to conservation. [00:37.96]So a rescue team tries to dislodge him [00:40.84]with waves from the bow of their boat. [00:43.87]But he's held fast. [00:46.21]His sunburnt skin quickly blisters. [00:49.61]The only option left is to use nets. [00:53.19]At last he's free.
