Chamaeleo zeylanicus, commonly known as the Asian Chameleon, has a fragmented distribution in Sri Lanka, India, and Pakistan (Nečas, 1999; Tilbury, 2019; Sindaco & al.). Itis the only chameleon species found in India. Its distribution spans the entire peninsular region of the country, from the Western Ghats to the Eastern Ghats, and extending into...
You would think the hardest thing about observing chameleons in the wild is finding them, when in fact the hardest thing is getting attached to seeing them day after day and then one day they are gone, either because they moved on or they died. They are endearing creatures that if you look closely you will see what makes each...
Chamaeleo ruspolii belongs to the least known chameleon species at all due to its restricted range in hardly accessible region in the Horn of Africa. Recently, evidence of their existence was secured almost a century after the last specimen was collected, Photos of life specimens are presented together with information on their biotope, and their...
Severe Case of Metabolic Bone Disease in Yemen Chameleon, Chamaeleo calyptratus (Sauria: Chamaeleonidae)
Chameleons can achieve impressive lifespans in captivity, contrary to the more common reports suggesting they typically live only a few years. This discussion draws on three case studies: females of Furcifer pardalis, a male Furcifer pardalis, and a male Calumma parsonii. These cases highlight significant age records for these species and analyze...

Chameleons exhibit color changes influenced by several factors. Primarily, they possess specialized cells called chromatophores that contain different pigments and can expand or contract to alter skin color. The guanophores retract the light on guanine crystal and ceeate additional color effects. Environmental factors such as temperature, light,...
New Species Chameleon Research in Madagascar: SEED Madagascar has recently identified a potentially new species of chameleon in the littoral forests of Sainte Luce, southeast Madagascar. Previously thought to be a known species, genetic evidence has revealed that this chameleon, referred to as Palleon cf. nasus, is genetically distinct. The...
The Nguru Mountains in Tanzania, known for their rich biodiversity, continue to astonish researchers with new discoveries. Recently, Joseph Mboya's expedition to this mountainous region highlighted a previously unidentified population of chameleons from the genus Rhampholeon. This genus is renowned for its unique morphological features, like...

Hissing in chameleons is a form of vocalization characterized by a sharp, exhaled sound produced when they force air through their glottis (the opening of the larynx). This sound is created by the rapid expulsion of air from the lungs, which passes through the glottis and vibrates the surrounding tissues, producing the characteristic hiss. The...
The Tiger Chameleon, Archaius tigris, inhabits the Seychelles islands of the Seychelles archipelago. Being a fragment of Gondwana, which is mostly submerged and preserved only as the highest peaks of the former mountains of the little continent, the Seychellois fauna is very unique and endemic, harbouring ancient faunistic and floristic elements of...
Chameleons are generally rather sensitive and nervous animals, and as such, they really do not like to be handled. For them, a huge object (like a human) might be ignored if it does not move, and they may even consider it a "walking tree" and crawl on it without problems. More likely, however, they perceive it as a predator. Therefore,...
Chameleons are best left alone, as they do not enjoy handling, they are wild animals that thrive when observed from a distance. However, there are specific scenarios—such as for research or captive management—where a keeper or breeder needs to know how to handle a chameleon safely, minimizing the risk of injury to both the animal and the handler.
Calumma oshaughnessyi, or O'Shaughnessy's chameleon, is found exclusively in the eastern rainforests of Madagascar. This species typically measures between 20 and 25 cm in length and exhibits colour variations from yellow, green to blue, often adorned white and blur spots. Mating males can have head coloured white or red. Breeding occurs during the...
Archaius tigris, commonly known as the tiger chameleon, is a relatively small chameleon species, measuring approximately 16 cm (6.3 in) in length. Its coloration ranges from subtle light-grey to vibrant yellow-orange, and it can also appear in shades of green or dark brown, often adorned with scattered black spots. A notable characteristic of this...
The gular area, or the so-called chin area is basically an area situated under lower surface of the body between the mental symphysis and the arc of the hyoid bone. In chameleons, it usually consists of three types of scales:
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.
To increase the heat gain and body temperature, the chameleons turn dark {Furcifer pardalis, Ankaramibe, Madagascar)
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:
