Rediscovery of a rare species in Madagascar reveals unprecedented details about behavior, appearance, and life cycle, after more than a century without confirmed scientific records, highlighting research challenges in remote environments and reinforcing the importance of conservation in threatened ecosystems.
A rare chameleon from Madagascar has returned to the scientific spotlight after researchers located live specimens of the species Furcifer voeltzkowi, known as Voeltzkow’s chameleon, during an expedition in the northwest of the island.
The reunion ended a gap of more than a century without confirmed records and also allowed for the detailed documentation of live females, something that the scientific literature had not described until then.
The rediscovery was associated with a targeted search conducted in 2018, near the historical locality of the species in Madagascar.

With 215 meters and a capacity for 28,000 tons of cables, a new giant ship has been launched to deploy underwater structures up to 4,000 meters deep on the seabed.
According to Re:wild, the mission lasted two weeks and placed the animal among the most emblematic cases of “lost” species rediscovered in recent decades.
The scientific work was published in October 2020 in the journal Salamandra, which treated the finding as a rediscovery accompanied by new evidence on morphology, genetics, and conservation.
Expedition in Madagascar finds 18 live chameleons
During the field campaign, the team recorded 18 live individuals, including three adult males, one adult female, and 14 juveniles.
This total appears in the scientific article as the set of animals observed and analyzed during the rediscovery, with data collection on coloration, body measurements, and genetic material.
The number drew attention because the species had remained off the scientific radar for decades, despite surviving in a restricted and hard-to-access area.
The study also clarified a point that is often simplified in popular accounts of the case.
The species had not been officially declared extinct on a global basis; it was treated as a “lost” animal, with no confirmed observations for a long time, and the Re:wild page itself presents it this way.
On the same page, the organization informs that the chameleon remained 107 years without records and still appears as not evaluated on the IUCN Red List.
Colorful females surprise researchers
Although the return of the chameleon to records was already enough to mobilize zoologists and conservationists, the most striking aspect of the discovery came from the females.
The article reports that males have predominantly green coloration, while females display a much more variable pattern and can show intense tones and unusual visual contrasts.
This sexual difference helped transform an almost unknown reptile into one of the most talked-about rediscoveries of that year.
Re:wild summarized this result by saying that the expedition not only rediscovered the species but revealed that the females are “very colorful.”
The scientific work is more cautious and states that female coloration is highly variable and can be extremely colorful, a relevant formulation because it avoids exaggerations and anchors the description in field observations.
Besides appearance, the study showed that the species is sexually dimorphic, with noticeable differences between males and females in body shape and head characteristics.
This expanded the available knowledge about the animal, which for a long time was known mainly from a few historical male specimens collected over a hundred years ago.
Short life cycle may explain disappearance
The researchers raise a plausible explanation for the prolonged disappearance: the life cycle of the Voeltzkow’s chameleon may be extremely short after hatching, in a pattern similar to that of Labord’s chameleon.
The article states that Furcifer voeltzkowi may live only a few months during the rainy season, spending much of its existence still in the egg.
This factor drastically reduces the window in which adults can be found in the wild.
This biological detail adds to a significant geographical obstacle.
The authors note that many roads in the occurrence area become inaccessible precisely during the wet period, when adult animals would be present.
In other words, finding the species depends not only on knowing where to look for it but also on reaching the habitat at the exact time of year.
Genetic difference confirms new classification of the species
Another relevant result of the research was the confirmation that the Voeltzkow’s chameleon is, in fact, a distinct species from Furcifer labordi, the Labord’s chameleon.
The authors compared morphology, coloration, and nuclear and mitochondrial DNA sequences.
The analysis concluded that there is sufficient differentiation to clearly separate the two species, although they are related.
This distinction has taxonomic and practical weight for science.
For decades, Furcifer voeltzkowi was treated as a synonym of other similar forms. This contributed to the scarcity of reliable data on distribution, biology, and conservation status.
Environmental pressures increase alert for conservation
The article estimates that the species’ occurrence area is about 1,000 km².
The researchers suggest that it meets threat criteria due to population fragmentation and continuous decline in habitat quality.
The landscape in the region is under pressure from environmental loss and degradation. This scenario is considered sensitive in Madagascar, an island recognized for its concentration of endemic species.
The rediscovery has both scientific and conservation value. It shows that a prolonged absence of records is not enough to end the story of a species.
It also indicates that finding a rare animal does not automatically resolve its future.
In the case of the Voeltzkow’s chameleon, the return to formal records came with a more solid foundation for studies and conservation.
In the realm of lost species, this case has also gained symbolic dimension.
Re:wild classified the chameleon as the sixth species on its most sought-after list to be rediscovered.
This data helps explain the international repercussions of the episode. The core of the discovery, however, remains scientific: a reptile described in the 19th century, last seen in 1913, has been studied again as a living organism.
