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 ...

Turtles have been classified in different ways by different authors. While they were previously considered anapsids , they are now considered more derived. [ 1 ] Recent analyses of molecular evidence have strongly suggested that they belong in the clade Archosauromorpha (also known as Archelosauria). [ 2 ]
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.

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]
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.
