Private keepers of chameleons often perpetuate the myth that chameleons cannot be cohabitated and that they should not see each other. While cohabitation in small enclosures is not advisable for multiple reasons, the belief that distant eye contact causes stress is false and belongs to outdated husbandry myths.
Researchers have discovered that anammox bacteria undergo surface color changes when subjected to prolonged starvation. This phenomenon is not driven by cytochrome c levels, as previously suspected, but rather by metabolic shifts that lead to iron-sulfur compound formation.
Influenza A virus is notorious for its ability to undergo frequent antigenic changes, earning it the nickname "The Chameleon Virus." Since its first isolation in the United Kingdom in 1933, researchers have identified key mechanisms that allow the virus to evade immune defenses and persist in human populations. The hemagglutinin (HA) protein plays...
Chameleons have been kept in captivity for centuries, with a significant rise in captive breeding beginning in the latter half of the 20th century. This trend continues to grow today. Initially, success in chameleon care meant keeping them alive for a few weeks or months. However, modern advancements have allowed some species to thrive for years...
The longitudinally lined pattern seen in Rieppeleon brevicaudatus appears to be more prevalent in neonates and juveniles compared to adults. This could be linked to an ontogenetic niche shift, where younger individuals primarily inhabit grass-level environments, while adults gradually transition to lower bush levels.
Chameleon_wifi_virus_common_cold Wi-Fi access points (APs) are devices that transmit and receive Wi-Fi signal. In other words, whenever you are accessing Wi-Fi, your device is connected to a Wi-Fi access point (wireless router). These devices are often left unprotected or have poor security in place. Until now, it was assumed that it was not...
In chameleon husbandry, extremely often, keepers and breeders swear that health issues which they want to consult and solve with a VET or in forums or FaceBook groups, appeared suddenly. They claim everything was fine for months or years and this means their husbandry must have been correct. They are badly mistaken.
Chameleons are not natural swimmers, but they can navigate through water when absolutely necessary. They seldom swim, typically doing so only when they accidentally fall into water or when they need to cross a body of water while moving to a new location.
Described as Chamaeleo dilepis martensi MERTENS 1964, it was escaping attention of the researchers... Compare its pictures to Chamaeleo dilepis, It is indeed a separate species.
Bill Strand, a global leader in chameleon popularization and education, has taken a bold step to fill a significant gap in chameleon literature—the care of hatchlings and neonates.
Researchers at the University of Illinois Urbana-Champaign have developed a UV-assisted direct-ink-write 3D printing technique that enables dynamic color changes during the printing process. Inspired by the structural coloration of chameleons, this method allows a single ink to produce a wide range of colors by controlling light exposure and...
Researchers at EPFL, Wageningen University, MIT, Yale, and Jülich Research Center have developed METEOR, an AI program designed to classify objects in satellite images with minimal training data. Unlike traditional AI models that require extensive datasets, METEOR can recognize new objects after being shown only a few images, making it highly...
Researchers at the American Chemical Society have developed a color-changing coating that mimics the thermal regulation abilities of the Namaqua chameleon. This innovative material adjusts its reflectivity based on temperature, keeping buildings cool in summer and warm in winter without additional energy input. The coating consists of thermochromic...
Researchers at the University of Minnesota Twin Cities have developed a revolutionary device called the catalytic condenser, which electronically modifies one metal to behave like another, enabling more efficient chemical reactions. This innovation opens the door for catalytic technologies using non-precious metal catalysts, reducing reliance on...
Researchers at Texas A&M University have developed a chameleon-like material by incorporating boron into vanadium dioxide, bringing it closer to mimicking brain cell activity. Vanadium dioxide is known for its metal-insulator transition, where it shifts between conducting and insulating states based on temperature. By introducing boron, scientists...
Researchers at the University of California, Riverside, have developed a nanomaterial that mimics chameleon skin, allowing robots to change color in response to movement. The material consists of gold nanorods fused with magnetic nanorods, encapsulated in a polymer shield. By controlling the orientation of these rods using magnets, scientists can...
Rosetta mission data has revealed how comet 67P/Churyumov-Gerasimenko undergoes color changes as it moves through space. The European Space Agency's VIRTIS instrument tracked the comet over two years, showing that its nucleus appeared redder when far from the Sun due to dust-covered surfaces. As it approached the Sun, sublimation exposed fresh ice,...
Researchers at Iowa State University have developed "chameleon metals"—materials that change their surface structure in response to heat. By treating liquid metal alloys with controlled heating, scientists observed the formation of tiny spheres and nanowires, altering the metal's surface texture. This breakthrough could lead to smart alloy...
Researchers at Rice University and the University of Texas Health Science Center at Houston have uncovered new insights into the role of the protein CPEB3 in long-term memory formation. CPEB3, described as a "chameleon-like" protein, interacts with actin-binding domains in neurons, forming stable aggregates that may store memory-related...
Chameleons are true masters of camouflage, using their unusual bodies, limbs, heads, and tails—often adorned with enlarged scales, horns, and various skin duplications or protuberances—to seamlessly merge with their surroundings, a classic example of Bayesian mimicry.
Quite often, we see private keepers of chameleons showing off pictures and videos of chameleons being fed with tweezers, usually offering a relatively large feeder like a roach or a locust. It is very enjoyable to watch a chameleon feeding using its long, extendable tongue with immense precision. However, this practice almost always provokes...
Chameleons are famous for their unique visual system, where each eye can move separately, allowing them to scan their surroundings monocularly. However, this study by Ketter Katz et al. (2015) challenges the idea that their eye movements are truly independent, showing coordinated tracking behavior when confronted with two separate visual targets.
A study published in BMC Evolutionary Biology explores the exceptional tree-climbing ability of chameleons, revealing that their ball-and-socket joints in wrists and ankles play a crucial role in their arboreal lifestyle. Researchers found that chameleons have twice the number of skeletal elements in their wrists and ankles compared to previously...
Until recently, Calumma vatosoa, a Malagasy chameleon species, was known only from a single male holotype and a photograph of another male specimen. In this study, David Prötzel et al. (2016) provide the first formal description of female C. vatosoa, expanding knowledge of its morphology and systematic position.
In 1992, Rhampholeon chapmani was described as a new species for science by Tilbury.
