CHAMELEONOLOGY: 

Water household in chameleons is a very complex area about which books can be written.

Chameleons are quite calm animals and do not proactively interact with humans unless they are forced to. In the wild, they are very efficient in escaping human attention - they are masters of disguise. In captivity, they are not true pets; they are pets for observation, not for handling, and certainly not for cuddling. Chameleons exposed to heat,...

Head bobbing is a common behavior observed in chameleons, particularly during social interactions, courtship, and territorial displays. This distinctive movement serves various purposes and plays a crucial role in their behavior and communication.

Furcifer pardalis, the Panther Chameleon is a chameleon species notoriously known for unbelievable and variable colors. Amongst all of them, one form situated in the extreme southwest of the range of the species exhibits spectacular and unbelievable red or pink colors. It is the form from the city of Ankaramibe.

Chameleons, in general, tend to display more blue coloration in captivity compared to the wild, as evidenced by numerous examples, especially in animals coming from several generations in human care. This blueing effect is notably present in Nosy Be panther chameleons (Furcifer pardalis), which naturally exhibit much less blue, with the so-called...

Chameleons are fascinating creatures known for their incredible ability to change color and their unique physical features. While they are generally harmless, bites can occur, particularly if they feel threatened or stressed. In this article, we'll discuss how to handle a chameleon bite and, more importantly, how to prevent bites from occurring in...

Candling chameleon eggs is a practice used by some breeders to assess the development of the embryos inside the eggs. While there are only questionable benefits to candling, there are several reasons why it is strongly adviceble not to do it:

Filariasis is caused by various filarial worms (such as Wuchereria bancrofti, Brugia malayi, and Loa loa in humans; Foleyella atum and Acanthocheilonema spirocauda in chameleons), which are transmitted through the bites of infected mosquitoes.

Chameleons possess two copulatory organs on the left and right sides, called hemipenes. These organs are situated in pockets at the base of the tail and can retract into them, controlled by a specific muscle that relaxes when the organ is extended.

Chameleons are extraordinary living beings that exhibit vibrant colors and unique behaviors, yet they are not exempt from the environmental devastation wrought by humans. The pervasive threat of microplastics is a growing crisis that affects all organisms and ecosystems, including these remarkable reptiles. As microplastics increasingly invade the...

Microplastics: The Silent Killer Choking Our Oceans and Devastating Life on Earth

The carpet chameleon, also known as the jewel chameleon or white-lined chameleon, is a species endemic to eastern central Madagascar. It is a relatively small chameleon, with males predominantly green and whitish or yellowish markings, while females display bright colors and varying patterns, including black, white, blue, yellow, and orange.

In 2012, A. M. Florio, C. M. Ingram, H. A. Rakotondravony, E. E. Louis, and C. J. Raxworthy published an article titled "Detecting Cryptic Speciation in the Widespread and Morphologically Conservative Carpet Chameleon (Furcifer lateralis) of Madagascar" in the Journal of Evolutionary Biology, Volume 25, Issue 7, pages 1399-1414. They confirmed that...

Once upon a time, it was actually about 2½ centuries ago, a very wise and educated nobleman came up with a brilliant idea of organizing all of our perceptions of the surrounding world, starting from rocks and minerals to plants and animals. This was Carolus Linnaeus, who wrote a book that became one of the most important works of mankind, called "...

The liver is a vital organ found in all vertebrates, including chameleons. Known scientifically as the "hepar" from the Latin term, the liver derives its name from the ancient Greek word "hēpar - ἡπαρ", which is transliterated as "hepar" into Latin. In chameleons, as in other reptiles, the liver plays a central role in metabolism, detoxification,...

In reptiles, the heart possesses a degree of autonomous regulation, allowing it to continue beating even after clinical death. This phenomenon is attributed to the intrinsic cardiac pacemaker within the heart. Specialized cardiac muscle cells can generate impulses independently of the nervous system, similar to the sinoatrial (SA) node found in...

Furcifer lateralis, commonly known as the carpet chameleon, is a striking species native to the highlands of Madagascar. This species is part of a recently revised species complex that now includes Furcifer viridis and Furcifer major. F. lateralis is primarily found in high-altitude grasslands, where it exhibits unique adaptations, and it...

Furcifer major is a captivating chameleon species that has undergone taxonomic clarification over the years. Long considered a synonym or subspecies of Furcifer lateralis, it was elevated to specific rank by Necas in 1996, a classification recently reaffirmed by molecular studies. This species is a member of the F. lateralis group, alongside F....

Chameleons are fascinating reptiles known for their vibrant colors and unique adaptations, which extend to their dental structure. One of the remarkable features of chameleon teeth is the presence of acrodont dentition. In this type of dentition, the teeth are attached directly to the crest of the jawbones, rather than being set in sockets like in...

Let us wish a Happy Christmas to the Yemen Chameleons! It has been around 40 years since the first offspring of Yemen Chameleons were born in captivity, and since then, this species has established itself in human care to the extent that they are now a regular pet worldwide. They have unfortunately been introduced by humans to other areas where...
