Fernandina giant tortoise
The species of giant tortoise called
chelonoidis phantastica disappeared more than a century ago and was long believed to be extinct. But in 2019, 112 years after the last sighting, researchers came across a single female tortoise. She was found living on Fernandina Island in the Galápagos, which is how she got her name. She is the only living example of her kind, as far as researchers know.
