Nature has a way of surprising us. Just when we think a species is lost forever, it reappears, defying the odds and reigniting hope for conservation. These “Lazarus species,” as they’re often called, are living proof of the resilience of life on Earth. In this article, I’ll take you through 11 incredible species that were once thought to be extinct but have miraculously reappeared. Their stories are a testament to the power of perseverance—both in nature and in the efforts of scientists and conservationists.
1. The Coelacanth (Latimeria spp.)
Thought Extinct For: 66 Million Years
The coelacanth, a prehistoric fish, was believed to have gone extinct alongside the dinosaurs. Imagine the shock when a living coelacanth was caught off the coast of South Africa in 1938! Today, two species of coelacanth are known to exist, offering a fascinating glimpse into the past.
Why It Matters
The coelacanth is often referred to as a “living fossil” and provides valuable insights into the evolution of marine life.
2. The Lord Howe Island Stick Insect (Dryococelus australis)
Thought Extinct For: 80 Years
After rats were introduced to Lord Howe Island in the early 20th century, this giant stick insect was declared extinct. In 2001, a small population was discovered on Ball’s Pyramid, a remote volcanic stack nearby.
Why It Matters
This insect’s rediscovery has sparked efforts to eradicate rats from Lord Howe Island and restore its ecosystem.
3. The Bermuda Petrel (Pterodroma cahow)
Thought Extinct For: 330 Years
The Bermuda petrel, or cahow, was believed to have been wiped out by invasive species and hunting in the 1600s. In 1951, 18 nesting pairs were found on remote islets in Bermuda.
Why It Matters
Conservation efforts have since increased the population to over 100 pairs, making it a symbol of hope for endangered seabirds.
4. The Takahe (Porphyrio hochstetteri)
Thought Extinct For: 50 Years
Native to New Zealand, the takahe was declared extinct in the late 19th century due to habitat loss and predation. In 1948, a small population was discovered in the Murchison Mountains.
Why It Matters
The takahe’s rediscovery has led to intensive conservation programs, including captive breeding and habitat restoration.
5. The New Guinea Singing Dog (Canis lupus dingo)
Thought Extinct in the Wild For: 50 Years
Known for their unique vocalizations, these dogs were believed to exist only in captivity. In 2020, a wild population was confirmed in the remote highlands of New Guinea.
Why It Matters
The rediscovery of these dogs provides an opportunity to study the origins of domesticated dogs and their role in ecosystems.
6. The Laotian Rock Rat (Laonastes aenigmamus)
Thought Extinct For: 11 Million Years
This rodent was known only from fossils until 2005, when it was discovered in a Laotian market. Its appearance was so unexpected that it was initially thought to be a new species.
Why It Matters
The Laotian rock rat challenges our understanding of mammalian evolution and highlights the biodiversity of Southeast Asia.
7. The Cuban Solenodon (Solenodon cubanus)
Thought Extinct For: 100 Years
This venomous mammal was believed to have gone extinct in the early 20th century due to habitat loss and predation by invasive species. It was rediscovered in the 1970s.
Why It Matters
The Cuban solenodon is one of the few venomous mammals and provides insights into the evolution of venom.
8. The Javan Elephant (Elephas maximus sondaicus)
Thought Extinct For: 1,000 Years
Once thought to have disappeared from Java, this subspecies of Asian elephant was rediscovered in Borneo in the 2000s, likely due to historical translocation.
Why It Matters
The Javan elephant’s rediscovery highlights the importance of genetic studies in conservation.
9. The Arakan Forest Turtle (Heosemys depressa)
Thought Extinct For: 90 Years
This rare turtle was believed to have been wiped out by habitat destruction and the pet trade. It was rediscovered in a Chinese food market in 1994.
Why It Matters
The Arakan forest turtle’s rediscovery has spurred efforts to protect its remaining habitats in Myanmar and Bangladesh.
10. The Terror Skink (Phoboscincus bocourti)
Thought Extinct For: 140 Years
This fearsome-looking skink, native to New Caledonia, was known only from a single specimen collected in the 1870s. It was rediscovered in 2003.
Why It Matters
The terror skink’s rediscovery underscores the importance of preserving remote and unexplored habitats.
11. The Crested Gecko (Correlophus ciliatus)
Thought Extinct For: 100 Years
Native to New Caledonia, the crested gecko was believed to have gone extinct until it was rediscovered in 1994. It has since become a popular pet.
Why It Matters
The crested gecko’s rediscovery highlights the role of hobbyists in conservation and the importance of protecting island ecosystems.
Why These Rediscoveries Matter
The reappearance of these species is more than just a scientific curiosity—it’s a reminder of the resilience of nature and the importance of conservation. These stories give us hope that even species on the brink of extinction can be saved if we act in time.
How We Can Protect Rediscovered Species
- Support Habitat Conservation
Protecting natural habitats is crucial for the survival of these species. Support organizations working to preserve forests, wetlands, and other ecosystems. - Combat Climate Change
Climate change threatens many of these species’ habitats. Reducing our carbon footprint can help protect their environments. - Promote Sustainable Practices
Encourage sustainable agriculture, fishing, and tourism to minimize harm to wildlife. - Fund Research and Monitoring
Continued research is essential to understand these species and develop effective conservation strategies. - Raise Awareness
Share the stories of these incredible species to inspire others to take action for conservation.
A Final Thought
The rediscovery of these 11 species is a powerful reminder that extinction is not always forever. Nature has an incredible ability to bounce back, but it needs our help. By protecting habitats, supporting conservation efforts, and raising awareness, we can ensure that these species—and countless others—continue to thrive. Let’s celebrate these incredible comebacks and work together to create a future where no species is lost forever.
