This is a Galapagos land iguana, and I'm wondering if it is an albino. Lots of pale, pinkish scales there, and even the eyes look pink. These reptiles vary in size from 3 to 5 feet in length, and can weigh upwards of 25 lbs, depending on which island you find them on.
On South Plaza island, where the populations of land and marine iguanas overlap, you even have cross breeding. This results in viable, though most-likely sterile, offspring. Poor little crossbred, sterile iguanalings, torn between land and sea. There's a tale to be told in there, maybe a children's book, maybe a coming of age Young Adult novella. Query your literary agent and see what they say.
