A Fernandina giant tortoise, long believed extinct and last seen over a century ago, has been rediscovered on Fernandina Island in the Galápagos archipelago, sending ripples of excitement through the scientific community. The finding confirms that Chelonoidis phantasticus, also known as the “fantastic giant tortoise,” is not extinct, offering renewed hope for the species’ survival.
Genetic analysis has confirmed the tortoise discovered in 2019 is indeed a Chelonoidis phantasticus, thought to have vanished more than 100 years ago. The discovery, made by a joint expedition between the Galápagos National Park and the Turtle Conservancy, has been hailed as a monumental achievement in conservation. “We initially suspected it might be from Española Island, another island in the Galápagos, because the saddleback morphology is not unique to Fernandina,” said Dr. James Gibbs, a tortoise expert at the State University of New York, in an interview with Yahoo News. “But the genetic analysis showed that it was indeed Chelonoidis phantasticus.”
The rediscovered female tortoise, estimated to be over 50 years old, was found in a patch of vegetation. The team is hopeful that there are other members of the species on the island, despite decades of searching turning up nothing. The single specimen has galvanized conservation efforts, sparking an intensive search of the island for additional members of its species.
The Rediscovery
The expedition that led to the rediscovery of the Chelonoidis phantasticus was part of a broader effort to survey the biodiversity of Fernandina Island. Fernandina, the youngest and westernmost island in the Galápagos archipelago, is characterized by its volcanic landscape and unique ecological niches. These environmental factors have shaped distinctive evolutionary pathways among the island’s fauna.
The team, led by Forrest Galante, a wildlife conservationist and biologist, meticulously scoured the island, navigating the difficult terrain. The discovery itself was a moment of immense excitement and relief. “Finding this tortoise confirms that Chelonoidis phantasticus is not extinct,” said Galante in a statement released shortly after the discovery. “It gives us hope, and it provides a crucial impetus to continue searching for other members of this species.”
Genetic Confirmation
Following the discovery, genetic samples were collected from the tortoise and sent to Dr. Gisella Caccone’s lab at Yale University for analysis. Dr. Caccone, a renowned expert in tortoise genetics, and her team compared the DNA of the rediscovered tortoise to that of a specimen collected in 1906. The genetic analysis provided definitive proof of the tortoise’s identity. “The genetic analysis unequivocally confirmed that the tortoise found on Fernandina Island is a Chelonoidis phantasticus,” Dr. Caccone explained. “It matched the genetic profile of the historical specimen, resolving any doubts about its species affiliation.”
The confirmation of Chelonoidis phantasticus‘s existence is not just a taxonomic victory, but also a victory for conservation science. It underscores the importance of genetic analysis in biodiversity research and highlights the potential for species to persist even when presumed extinct.
Characteristics of Chelonoidis phantasticus
Chelonoidis phantasticus, or the Fernandina giant tortoise, is notable for its uniquely shaped shell. Characterized by a saddleback morphology, particularly pronounced in males, this shell shape is an adaptation to the island’s environment. The tortoise’s shell features prominent projections along its upper margin, contributing to its “fantastic” appearance. The specimen discovered in 2019 exhibits some of these characteristics, though as a female, the saddleback shape is less pronounced.
The tortoises are thought to have evolved in isolation on Fernandina Island, leading to their distinctive traits. Their diet likely consists of vegetation native to the island, including grasses, leaves, and cacti. Giant tortoises play a critical role in their ecosystems as seed dispersers and herbivores.
Conservation Implications
The rediscovery of Chelonoidis phantasticus has profound implications for conservation efforts in the Galápagos Islands. The finding underscores the resilience of life and the potential for species to persist in the face of habitat loss and other threats. It also highlights the need for continued monitoring and conservation efforts in the Galápagos, a region renowned for its biodiversity.
Conservationists are now focused on determining the size and composition of the remaining population of Chelonoidis phantasticus on Fernandina Island. This will involve intensive surveys of the island, using advanced tracking technologies and traditional field methods. The aim is to locate additional individuals and assess the genetic diversity of the population.
“Our top priority is to find more tortoises on Fernandina Island,” stated Danny Rueda Córdova, the director of the Galápagos National Park. “We are committed to dedicating the resources necessary to conduct a comprehensive search and protect this species from extinction.”
Threats to Survival
Fernandina Island, while relatively untouched by human development, faces several environmental challenges. Volcanic activity, a natural part of the island’s ecosystem, can disrupt habitats and impact tortoise populations. Introduced species, such as rodents, also pose a threat by preying on tortoise eggs and young tortoises.
Conservationists are implementing strategies to mitigate these threats. These include controlling invasive species, monitoring volcanic activity, and developing a captive breeding program. The goal is to ensure the long-term survival of Chelonoidis phantasticus and maintain the ecological integrity of Fernandina Island.
Captive Breeding Program
A captive breeding program may be essential for the long-term survival of Chelonoidis phantasticus. If additional tortoises are found, they could be brought into a controlled environment where they can breed and produce offspring. These offspring could then be reintroduced to Fernandina Island, bolstering the wild population.
The Galápagos National Park has extensive experience in captive breeding of giant tortoises. They have successfully bred other species of Galápagos tortoises, including those from Española Island. This expertise will be invaluable in any efforts to breed Chelonoidis phantasticus.
