Santa Fe Island tortoise
The Santa Fe Island tortoise, also known as the Santa Fe tortoise or Santa Fe giant tortoise, is an undescribed extinct taxon of Galápagos tortoise endemic to Santa Fe Island in the Galápagos archipelago in the equatorial eastern Pacific Ocean. Evidence for the historic existence of the tortoise comes from 19th century anecdotes of whalers and settlers removing tortoises from the island, as well as the discovery of tortoise bones there by the 1905–1906 California Academy of Sciences expedition, with genetic examination of the bones indicating that they belonged to a unique taxon most closely related to Chelonoidis niger hoodensis, the Hood Island giant tortoise from Española Island.
