Chameleons do not primarily change their coloration to blend with the environment, but use it mainly for communication and thermoregulation purposes. A very special case occurs when females, due to changes in hormonal levels, begin to show a very specific coloration after conception.

Researchers from the African Amphibian Conservation Research Group, led by Fortunate M. Phaka, studied the use of chameleons in traditional medicine at urban markets in South Africa, visiting six cities. They identified 33 species of reptiles and one amphibian species used for medical purposes. Interviews with 11 traditional healers revealed that...

After several weeks of gravidity, female chameleons descend to the ground to deposit their eggs, leaving them alone for the months required for incubation. During this time, the females become quite heavy and less agile, making them vulnerable. Consequently, this process typically occurs in a secretive and rapid manner. Observations of females...
Many captive chameleons die in terrible pain due to respiratory infections. The primary cause is improper captive parameters, specifically a combination of:
Hydration Using Ice Cube?
One of the hydration methods in chameleon husbandry, in addition to nighttime fogging and misting, is the use of liquid water from various drippers. These can be purchased at pet stores or improvised using a cup with a perforated bottom or a similar contraption. A simple approach is to place an ice cube on the mesh top of the cage,...

Welcome to the curious world of chameleons and their rather fascinating and flamboyant hemipenes — yes, that's right, not just one, but two of these ornate copulatory organs! When it comes to reptilian romance, they certainly don't skimp on the bling. Better yet, the name itself might just tickle your linguistic fancy.
Chameleon Hemipenes and Hemipeneal Plugs
Chameleons are fascinating reptiles known for their unique appearance, features and strategies. One of their noteworthy biological features is the presence of two copulatory organs called hemipenes (singular hemipenis). These structures are located in specialized pockets at the base of their tails, known as "hemipeneal pockets".
What Do Chameleons Do When It Rains?
When they are thirsty, they drink.
When they are well hydrated, they hide from rain and sleep.
White Namaqua Chameleon Born in Captivity
In November 2023, a remarkable piece of information was shared on Facebook regarding the appearance of a leucistic, patternless Namaqua chameleon, Chamaeleo namaquensis, among offspring of this species in captivity. This animal is extraordinary and has never been reported in the wild. Its unique white coloration, devoid of any protective melanin,...
Based on analysis of the East African populations of Chamaeleo dilepis - complex, the following surprising taxonomic changes are made:

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...
Did You Know: Chameleons Can Eat Birds?
...they can shoot, kill, chew, swallow and digest them…
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...
