[00:00.0]Southeast of Hawaii, [00:02.19]straddling the equator, [00:04.4]lie the Galapagos Islands [00:07.0]As on Hawaii, [00:08.71]some of the volcanoes here are still very active [00:12.37]The coastline of Isabela - the largest island [00:16.32]- is covered in volcanic rock [00:18.46]Here a very different kind of animal can be found in the rocky tubes [00:23.38]The chicks of Galapagos penguins [00:26.86]Without the lava tubes, [00:28.30]they wouldn't survive [00:30.0]Cool and sheltered, [00:31.51]the tubes are the perfect nursery, [00:33.71]protecting the chicks from the unforgiving temperatures outside [00:37.60]Unforgiving if you're a penguin,that is [00:40.66]Adult Galapagos penguins only cope by doing something the chicks can't yet do [00:45.67]They take a dip [00:47.0]The adults plunge into cool waters [00:48.86]that have travelled all the way from the Antarctic [00:51.84]Who says penguins can't fly? [00:55.21]There's lots of food here, [00:56.76]as schools of fish are drawn to the shelter of these rocky, volcanic shores [01:01.61]But while the parents are out fishing, [01:04.88]their chicks are home alone [01:08.17]Back in the lava tube, [01:09.82]there's something creeping around [01:13.1]A Sally Lightfoot crab has penguin on its mind [01:16.87]It's dark, [01:17.99]so the crab can't be sure exactly what it's up against [01:21.78]This time, it's taken on more than it can handle [01:25.0]Had the encounter been just a few days earlier, [01:27.87]the outcome might have been very different [01:30.14]Crabs are major predators of baby penguins
