Photograph by @mattiasklumofficial for @natgeo. A Galapagos land iguana having a spiny meal on Isabela Island, Galapagos. Since fresh water is scarce on the Galapagos islands the gorgeous land iguana obtains the majority of its moisture from the prickly-pear cactus that makes up roughly 80% of its diet. Go to @mattiasklumofficial to see more images from the Galapagos Islands and other unique realms! It is estimated that between 5,500 and 9 500 land iguanas are found in the Galapagos. These iguanas were so abundant on Santiago Island at one time that famed naturalist Charles Darwin remarked at the time when it was called King James Island that "when we were left at James, we could not for some time find a spot free from their burrows on which to pitch our single tent". In the years since then, entire populations (including all the animals on Santiago Island) have been wiped out by introduced feral animals such as dogs, cats, rats and pigs. #galapagos #landiguana #isabelaisland #conservation #darwin #protect #cactus #photooftheday #instagood #mattiasklum #evolution #bonapetit #iucn @thephotosociety @natgeo @mattiasklumofficial @natgeocreative
