Climates of Change: A Tuatara’s-Eye View

Abstract

The tuatara or New Zealand “spiny-backed lizard” (Sphenodon punctatus) is the sole surviving member of an order of reptiles that pre-dates the dinosaurs. Among its characteristics and peculiarities, the tuatara is renowned for being slow-breathing and long-lived; it possesses a third eye on the top of its skull for sensing ultraviolet light; and the sex of its progeny is determined by soil temperatures. This article unravels a tuatara’s-eye view of climate change, considering this creature’s survival across geological epochs, its indigenous lineage and its sensitivities to the fast-shifting conditions of the Anthropocene. This article examines the tuatara’s evolving role as an icon of biodiversity-under-threat and the evolving role of zoos and sanctuaries as explicators of climate change, forestallers of extinction, and implementers of the reproductive interventions that are increasingly required to secure the future of climate-vulnerable species. It is also interested in the tuatara as a witness to the rapid and ongoing human-wrought climate change which has secured the lifeworld reconstruction that is foundational to the settler colonial enterprise in Aotearoa/New Zealand. Linking this to the Waitangi Tribunal’s Wai 262 report (Ko Aotearoa Tēnei, 2011), the article considers what the tuatara teaches about kaitiakitanga (guardianship) and climates of change.
