The tortoise has been transferred to a breeding center for the purpose of conservation and genetic tests. [45] [46] Only one confirmed individual, but others may still exist. Fernandina (Narborough) Island C. n. porteri Western Santa Cruz Island tortoise. Conservation status Critically Endangered [47] Rothschild 1903 [48]
Captive Galapagos tortoises can live up to 177 years. [4] For example, a captive individual, Harriet, lived for at least 175 years. Spanish explorers, who discovered the islands in the 16th century, named them after the Spanish galápago, meaning "tortoise". [5] Galápagos tortoises are native to seven of the Galápagos Islands.
Santa Cruz giant tortoise Bottlenose dolphins jumping off the Galápagos Islands. One of the best-known animals is the Galápagos tortoise, which once lived on ten of the islands. Now, some tortoise species are extinct or extinct in the wild and they live on six of the islands. The tortoises have an average lifespan of over 130 years.
The tortoise population of Floreana is estimated to have originally comprised some 8,000 individuals. Extinction occurred during the 1840s or 1850s following overexploitation for food by sailors and settlers, as well as predation and habitat degradation from introduced species, including goats, pigs, dogs, cats, donkeys, and rodents.

Although relatively undisturbed by whalers, fairly large numbers of tortoises were removed by expeditions in the latter half of the 19th century and the early 20th. After the introduction of black rats (Rattus rattus) and brown rats (Rattus norvegicus) [4] some time before 1900, no natural breeding succeeded. Since 1965, eggs have been ...
The Galápagos tortoise, whose protection from extinction impulsed the Project Isabela. The Project Isabela (Spanish: Proyecto Isabela) was an environmental restoration project in the Galápagos Islands of Ecuador that took place between 1997 and 2006, [1] initiated by the Charles Darwin Foundation and the Galápagos National Park.
The Galapagos Conservancy has reportedly launched further expeditions to Fernandina Island searching for a male tortoise, rebuffing Galante’s attempts to collaborate again. [ 21 ] On May 25, 2021, officials announced that genetic tests had confirmed that the female tortoise found in 2019 is indeed a member of the Chelonoidis niger ...
Charles Darwin depicted in an engraving with three species of Galápagos tortoises, including C. n. microphyes (Cassell's Natural History, 1878) The tortoise population is estimated to comprise some 500–1,000 mature individuals, a decline of 94% since 1840, and the subspecies is considered to be Endangered. The tortoises were historically ...
