Three giant Galapagos tortoises in London Zoo have moved into a new home after growing out of their old enclosure. The sisters, named Polly, Dolly and Priscilla, arrived at the zoo over ten years ago and have doubled in size since. Their new area is much more spacious and mirrors their natural habitat with climate control and humidity boosters. Report by Buseld.
