CHAMELEONOLOGY: 

Chameleon Natural History...


Among chameleons, the coloration of hatchlings varies strikingly across species. While many species produce relatively uniform offspring that only later develop the complex adult palette, others astonish with vivid diversity from the very beginning.

The myth is misleading if taken literally as "hollow." The tongue tip is not an empty cavity, but its prey-catching mechanism does involve a suction-like effect. The centrally positioned retractor muscle contracts to create pressure dynamics at the tongue pad, allowing the tip to act partly like a suction cup. This suction effect works in concert...

Structural colouration, rather than pigment, is a rare phenomenon in biology. This article compares the metallic blue fruit of Elaeocarpus angustifolius (blue quandong) with the non‑pigmentary blue of chameleons (Chamaeleonidae). Both achieve their colour through nanoscale arrangements that manipulate light, yet they belong to evolutionary lineages...

Furcifer balteatus is a striking Malagasy chameleon, first described by Duméril and Bibron in 1851. The species belongs to the genus Furcifer, which encompasses many of Madagascar's large-bodied chameleons. The name balteatus derives from the Latin, meaning "belted" or "girdled," a reference to the distinctive transverse banding pattern that...

Calumma hilleniusi is a rare chameleon species endemic to Madagascar, described by Brygoo and Domergue in 1973. It is restricted to the Ankaratra Massif in the central highlands, making it a true microendemic with an extremely limited distribution. The species inhabits montane rainforest fragments at high elevations, where cool and moist conditions...

Calumma malthe is a Malagasy chameleon described by Günther in 1879. It belongs to the family Chamaeleonidae and is endemic to eastern and northeastern Madagascar. The species inhabits humid evergreen forests and mountain cloud forests, with known populations in areas such as Andasibe, Anjanaharibe-Sud, and Marojejy National Park. It is...

The veiled chameleon (Chamaeleo calyptratus) has long fascinated biologists with its ornate casque, a cranial crest that rises like a crown above its head. Recent research has transformed our understanding of this structure by building the first comprehensive three‑dimensional anatomical atlas of male and female chameleon heads. Using...

Meet the Arizona black rattlesnake (Crotalus cerberus)—a serpent with a secret superpower. Nicknamed the "chameleon rattlesnake", this species can pull off something almost unheard of in the snake world: rapid color change.

Walking through a wonderful rainforest in eastern Madagascar, two of my guides confronted me with a very strange question: Is it true that chameleons have two brains? They explained that tourists had repeatedly told them this. The justification was that the huge eyes move independently, each receiving separate pictures of the environment, and...

In the realm of naturalistic chameleon husbandry, the interior of the enclosure must reflect the biome it seeks to emulate. Natural branches—alongside living plants—are the only suitable climbing structures. Artificial substitutes such as ropes, fabrics, plastics, fake vines, exposed lumber, bamboo, ladders, or swings are categorically unsuitable....

A story circulates that two veiled chameleons (Chamaeleo calyptratus) with unusual white markings were discovered on a branch in Yemen. A local man supposedly sold them to an animal trader, who exported them to the United States, founding the "translucent" breeding line.

It may look spectacular to watch a chameleon fire its tongue at prey held in your hand or with tongs. But this practice is dangerous and can cause permanent injury. What seems entertaining can cripple the animal for life.
