Fernandina Island Galápagos tortoise
Chelonoidis niger phantasticus (commonly known as the Fernandina Island Galápagos tortoise or Narborough Island giant tortoise) is a subspecies of Galápagos tortoise that was discovered in 1906 and thought extinct, until a single female was discovered living on Fernandina Island by an expedition in February 2019. In May 2021, a genetic test carried out by scientists from the California Academy of Sciences confirmed that the single female tortoise discovered in 2019 is from the subspecies Chelonoidis niger phantasticus. The subspecies name has often been misspelled as phantastica, an error introduced in the 1980s when Chelonoidis was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017. Taxonomy Chelonoidis niger phantasticus is considered a subspecies of Chelonoidis niger, sometimes considered a valid species itself alongside all other subspecies. Rhodin et al. (2010) lists them separately but under the heading "C. niger species complex". Discovery and rediscovery Originally known from only one male specimen found (and killed) by members of the 1906 California Academy of Sciences expedition, there were discoveries of putative tortoise droppings and cactus bite marks in 1964 and 2013, and an unconfirmed sighting in 2009. No confirmed live tortoises nor remains were found on
