This is a Tuatara - and it is not a lizard. . . . "Tuatara are rare, medium-sized reptiles (adults ranging from about 300g to 1000g) found only in New Zealand. They are the only extant members of the Order Sphenodontia, which was well represented by many species during the age of the dinosaurs, some 200 million years ago. All species apart from the tuatara declined and eventually became extinct about 60 million years ago. Tuatara are therefore of huge international interest to biologists and are also recognised internationally and within New Zealand as species in need of active conservation management." . . . They live for 60 - 100 years.Tuatara have a third eye on top of the brain between the visible other eyes. Although this eye has no vision, it is light sensitive. A fascinating creature and easy enough to photograph as they don't move much :) This was taken from a distance so clarity not good. Tuatara means ‘spiny back’ in Maori.
