The New Caledonian Giant Gecko (Rhacodactylus leachianus) is native to Grande Terre and surrounding satellite islands. These geckos are massive -- growing in total length between fourteen to seventeen inches. Along with their robust size, this species has a great number of vocalized calls that even sound like grumbles or whistles. The smaller sized island specimens (previously Rhacodactylus leachianus henkeli) are amazingly colorful! The most common locality specific giant geckos are the Nuu ami, Nuu ana, Morro (Island E), and Yate.
