Scientists have rediscovered an elusive chameleon in Madagascar that was last seen over a century ago. The Voeltzkow’s chameleon is a unique species that have a lifespan of just a few months during the rainy season in northwestern Madagascar. Until the spring of 2018, this species had not been spotted since 1913.

The female chameleon had never been documented before and the study notes that their colouration is “highly variable and can be extremely colourful.” The researchers say that when stressed, the dark green stripes on the females change to black, a violet stripe appears and runs from their cheek to the basis of the tail, and white and black speckles appear on parts of their tail and head. Alternatively, the males largely remain green throughout their lives.

This Remarkable Chameleon Disappeared 107 Years Ago. It Just Returned.

From Popular Mechanics

In 1913, Voeltzkow’s chameleon (Furcifer voeltzkowi) disappeared from the wild, never to be seen in its native Madagascar again. But now, more than a century after scientists thought they had long lost the elusive creature to time, they’ve surprisingly rediscovered it once more.

The reptile’s reemergence is the result of a push from the Global Wildlife Conservation, whose Search for Lost Species program seeks to find species that scientists haven’t spotted for at least a decade, according to Live Science.

Researchers began combing Madagascar for the chameleon in March 2018, but they came up empty until the expedition was nearly over. With just days left in the journey, a professional guide spotted one of the chameleons—and then the floodgates opened.

The researchers ultimately rediscovered three males and 15 females in

How This Chameleon Got Lost And Found Again

Chameleons are known for their hide-and-seek prowess, but one species, Voeltzkow’s chameleon, took the game to a whole new level. The elusive lizard lives deep in the forests of northwestern Madagascar, and no one had spotted it since 1913. Many zoologists had even begun to doubt that the species ever really existed. The handful of specimens that scientists described in the late 1800s must actually have been funny-looking members of another species, the rhinoceros chameleon, they said.

In a recent paper, however, zoologist Frank Glaw and his colleagues announced that they had found and studied several Voeltzkow’s chameleons during a spring 2018 expedition to northwest Madagascar.

Scientists Find Madagascar Chameleon Last Seen 100 Years Ago | World News

Talk about good camouflage!

Scientists say they have found an elusive chameleon species that was last spotted in Madagascar 100 years ago.

Researchers from Madagascar and Germany said Friday that they discovered several living specimens of Voeltzkow’s chameleon during an expedition to the northwest of the African island nation.

In a report published in the journal Salamandra, the team led by scientists from the Bavarian Natural History Collections ZSM said genetic analysis determined that the species is closely related to Labord’s chameleon.

Researchers believe that both reptiles only live during the rainy season — hatching from eggs, growing rapidly, sparring with rivals, mating and then dying during a few short months.

“These animals are basically the mayflies among vertebrae,” said Frank Glaw, curator for reptiles and amphibians at the ZSM.

Researchers said the female of the species, which had never previously been documented, displayed particularly colorful patterns during pregnancy, when

A flexible color-changing film inspired by chameleon skin — ScienceDaily

Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces.

By tensing or relaxing their skin, chameleons can change the way light reflects from guanine crystals under the surface, producing what’s known as structural coloration. These structural colors are different from the pigments that give many other creatures their hues. Scientists have mimicked the crystalline nanostructures of chameleon skin in various color-changing materials, but they’re typically difficult to produce, or they rely on non-renewable petroleum resources. In contrast, cellulose nanocrystals are a renewable material that can self-assemble into a film with iridescent structural colors. However, the films
