Fern is a unique case because she was only discovered in 2019; the Fernandina Island tortoise species was presumed extinct for over a century. Last spotted in the wild in 1906, the species was brought back to life (barely) thanks to Fern’s discovery, in a great moment for conservation. But she still is the only known member of her species, qualifying her for this list of endlings.
