Endling: The Story of Lonesome George

Maeve Kiley

Discovery

In 1971, scientists arrived on Pinta Island, Ecuador, on an expedition. Hungarian scientist József Vágvölgyi was studying native snails when he stumbled upon a truly miraculous discovery.

Hidden amongst the spiky Opuntia Cactus and sloping Palo Santo trees, a single Pinta tortoise sat. Munching on cactus pads and resting in the hot sun, he was living the traditional tortoise life. Except he was living all alone.

Lonesome George

The tortoise did not know who these scientists were. He did not know what the Charles Darwin Research Center was or what “endangered” meant. He did not even know what the great burden placed upon his shell was. This tortoise, soon to be named “Lonesome George,” was an endling - the last of his kind.

The Lives & History of the Pinta Island Tortoise

Pinta Island is north of the Galapagos Islands. It is secluded, and the native animals did not experience permanent human inhabitants. It is home to countless species, unique to the area. The Pinta Island tortoise is a subspecies of the Galapagos tortoise. They are an immensely large tortoise with a distinct saddleback-shaped shell and long neck. They consumed native greens, grasses, fruits, and cactus pads. They utilized their long necks to reach their food and their heavy feet to dig for roots. The species possessed slow metabolisms, so most of their behavior revolved around rest and soaking up nutrients from the hot sun. The tortoises formed mutualistic relationships with local finches and flycatchers. The birds would pick and eat bugs off the tortoises’ long necks. Their grazing, seed dispersal, and bonds with other animals made Pinta Island tortoises a keystone species.

Western ships arrived on Pinta Island in the 15th century. Led by the Spanish Bishop Tomás de Berlanga, the island was left uncolonized due to its dry and rugged terrain. However, the island became an ideal hideout for pirates and a supply stop for whalers in the 18th and 19th centuries. This way station proved disastrous for the local wildlife. Sailors and pirates slaughtered thousands of native whales and tortoises for oil. Many were captured and held as living captives for months without food or water.

In 1959, local fishermen released goats on the island. The invasive animals devoured most of the vegetation, decimating the tortoises’ food supply. George is estimated to have hatched in 1911. By the time George had reached maturity, he was all alone

Endlings

National Geographic defines endlings as simply “the last member of a species.” Endlings serve as a haunting reminder of the real threat of extinction and the cost of unchecked human expansion and consumption.

Lonesome George may have been the last member of his species, but he was not alone in his status. One of the earliest and most famous Endlings was Martha the Passenger Pigeon. In the 19th and early 20th centuries, commercial hunters and widespread habitat destruction decimated Passenger Pigeon populations. A population that once flourished in the billions plummeted to a single pigeon who died at age 29 at the Cincinnati Zoo.

The last known male northern white rhinoceros, Sudan, died in Kenya in 2018. Trophy hunters and habitat loss drove his subspecies to the brink of extinction. Only two northern white rhinos remain: his daughter, Najin, and his granddaughter, Fatu. With no remaining males, Najin and Fatu are Endlings, and their deaths will mark the end of the species.

            Scientists discovered the Rabbs’ fringe-limbed treefrogs in the mountains of Panama in 2005. Conservationists collected a small group of frogs to save the species from a deadly fungal disease. The situation worsened with their entire population local to a small area that was rapidly losing habitat. The captive breeding program failed, and Toughie lived alone in a specialized biosecure enclosure in Atlanta. He passed away in 2016, only four years after the previous frog died. This loss was heartbreaking. The Rabbs’ fringe-limbed treefrog was an exceptionally unique subspecies of treefrog with fully webbed hands and feet that allowed them to glide between tall trees. The treefrogs were also famous for their beautiful call. Toughie remained mostly quiet in captivity, but researchers recorded him calling one night in late 2014.

An Important Legacy

            Lonesome George was transported to the Charles Darwin Research Station on Santa Cruz Island for protection. He lived in corral care for four decades, with dedicated park rangers providing him with attentive, round-the-clock care. Conservationists attempted to breed him with closely related female tortoises, but mating attempts yielded infertile eggs. News outlets and scientific organizations brought international attention to Lonesome George’s life and story.

            He died of natural causes on June 24, 2012, at the Galapagos National Park breeding center. Conservators carefully mounted his preserved body for educational display at the Fausto Llerena Breeding Center on Santa Cruz Island.

            Although the research station staff provided Lonesome George with excellent care, he never belonged in captivity. The recklessness with which the lives of his species, as well as countless other species, were handled dramatically altered the course of his life.

Pinta Island is preserved as a conservation site, but still faces serious threats from invasive species. Although the world lost these tortoises, we can still act to protect other species. Mammals, reptiles, amphibians, birds, insects, fungi, flowers, marine life, trees, and all other forms of natural life face the threat of extinction daily due to deforestation, climate change, pollution, trophy hunting, habitat loss, and invasive species. Human overexploitation comes with a painful price of which the entire world feels the ripples.

Lonesome George’s legacy continues. The world must remember George, Sudan, Martha, Toughie, Najin, Fatu, and the many unnamed species that depend on societal and legislative changes to protect their homes and lives.
