CHAMELEONOLOGY: 

Chameleon Natural History...


Brookesia brunoi, described in 2012, is a leaf chameleon endemic to Madagascar's south‑central highlands. It belongs to the Brookesia decaryi group and is distinguished by its robust morphology and cryptic coloration. Adults reach up to 68 mm in total length, making it medium‑sized for the genus. The dorsal surface carries nine pairs of...

Furcifer minor, the so‑called lesser chameleon of Madagascar's central plateau, is anything but modest in appearance. Both males and females exhibit striking coloration that makes this species one of the more visually impressive members of the genus. Males often display bold greens and yellows, accented with contrasting lateral striping that...

The Tamatave population of Furcifer pardalis, one of Madagascar's most iconic panther chameleons, is renowned for its remarkable seasonal variability in coloration. Males in this coastal region typically exhibit more cryptic tones during the dry season, blending into their environment with subdued greens and browns that provide effective...

Calumma crypticum, also known as the blue-legged chameleon, is a montane species endemic to Madagascar's rainforests. First described by Raxworthy & Nussbaum in 2006, it had long been confused with Calumma brevicorne until genetic and morphological differences confirmed its distinct status. The species name reflects its previously "cryptic"...

Chameleons are said to be strictly solitary creatures. Popular advice claims that even visual contact between individuals causes extreme stress, potentially leading to death. This belief has led to widespread recommendations for opaque cage dividers and isolation protocols in captivity.

It is a widespread misconception that placing light bulbs directly inside terrariums or cages provides the most effective illumination and heat. In reality, this practice is against EU electrical installation norms and poses serious safety risks.

Fieldwork with chameleons often reveals behaviors that are as surprising as they are spectacular. One recurring observation, especially in Furcifer pardalis (the panther chameleon), is that individuals frequently defecate when photographed or gently manipulated. After hundreds of encounters in Madagascar, this has proven to be a consistent...

In north‑western Madagascar, Furcifer oardalis displays a basic ground coloration that serves as a canvas for striking variation. Across this base tone, many individuals bear crossbars, often of spectacular intensity, ranging from vivid greens and blues to contrasting reds and yellows. These color patterns are not uniform across the species' range;...

Brookesia minima, described by Boettger in 1893, is a dwarf chameleon species confined to Nosy Be and Nosy Komba off Madagascar's northwest coast, with records also from the Manongarivo Reserve on the mainland. Known by common names such as the Madagascar dwarf chameleon, minute leaf chameleon, and Nosy Be pygmy leaf chameleon, it was long...

When I first visited Nosy Be in 2007, the island seemed intact, its reptilian inhabitants thriving. By 2019, however, I observed a disturbing shift: nearly half of the females of Furcifer pardalis displayed male-like traits. This year, the phenomenon has intensified—most females now exhibit these strange characteristics, with the exception...

Furcifer viridis is a striking chameleon species from Madagascar and a typical representative of the Furcifer lateralisgroup. True to its name, which means "green," this species is most often adorned in vivid emerald tones that dominate its body. The green coloration provides excellent camouflage among foliage, allowing it to blend seamlessly into...

The giant Oustalet's chameleon (Furcifer oustaleti) is one of Madagascar's most imposing reptiles, reaching lengths of up to 60 centimeters. Despite its impressive size, its coloration is usually quite cryptic, blending into tree bark and foliage with earthy browns and greys that provide effective camouflage. Yet, across Madagascar, regional...

The panther chameleons of Diego Suarez, at the northern tip of Madagascar, are among the most visually arresting of all regional morphs. Males in this population exhibit a dazzling palette that sets them apart from their counterparts elsewhere. Their bodies shimmer in vivid green tones, overlaid with a bright yellow wash that illuminates their...

Furcifer pardalis, the celebrated panther chameleon of Madagascar, is famed for its dazzling regional color morphs. In Montagne d'Ambre, a volcanic massif in the north, this species has developed a particularly striking pattern that sets it apart from other populations. Individuals here display a high yellow background across their bodies, a...

Furcifer petteri, a rare chameleon species native to northern Madagascar, is renowned for its striking sexual dimorphism and seasonal coloration. In their natural habitats, these chameleons typically display gren tones that help them blend into foliage and branches. Yet, during reproductive periods, females undergo a remarkable transformation. When...

Brookesia antakarana, a robust leaf chameleon species endemic to northern Madagascar, thrives in the leaf litter of humid forests where its cryptic coloration provides excellent camouflage against predators. Typically, these reptiles blend seamlessly with their environment, appearing in muted browns and greys that mimic decaying leaves and forest...

Chameleons represent a lineage of lizards whose ecological strategies are deeply tied to arboreal life. Their morphology, physiology, and behavior are adapted to vertical habitats, where foliage provides both concealment and microclimatic stability. Yet, exceptions exist: desert-dwelling Chamaeleo namaquensis, forest-floor specialists (Brookesia,...

Chameleons are evolutionary specialists designed to subsist on prey of extremely low energetic value. Their natural diet is dominated by flying insects—bees, wasps, flies, beetles—and orthopterans. They rarely, if ever, encounter larvae of beetles, moths, or butterflies; their access is almost exclusively to adults.
