The Galapagos Tortoise Movement Ecology Programme is a collaborative project coordinated by Dr Stephen Blake of the Max Planck Institute for Ornithology. Its goal is to assist the Galapagos National Park to effectively conserve giant tortoises by conducting cutting-edge applied science, and developing an inspirational tortoise-based outreach ...
Sierra Negra giant tortoise. Conservation status Critically Endangered [31] Baur 1889 [32] Severely depleted by settlement and exploitation for oil which continued until the 1950s. The wild reproduction is successful in the east, but in the western-southwestern area, rats, dogs, cats and pigs are present as predators.
Chelonoidis niger vandenburghi, also known as the Volcán Alcedo giant tortoise, the Alcedo Volcano giant tortoise or the Alcedo giant tortoise, is a subspecies of Galápagos tortoise endemic to the Galápagos archipelago in the equatorial eastern Pacific Ocean. The specific epithet vandenburghi honours American herpetologist John Van Denburgh. [3]
The now-extinct West Indian radiation is thought to group with the Chaco and Galapagos tortoises but is significantly basal to both, and was a rather evolutionary distinct lineage, having diverged well before any of the modern species in the genus did and only 7 mya after the divergence of Chelonoidis from African tortoises.
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.

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.

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.
