Chamaeleo necasi is a medium‑sized West African chameleon of the Chamaeleo dilepis group, documented from southern Togo and adjacent Benin. It is associated with lowland forest and ecotonal woodland below roughly 500 m, though detailed microhabitat information has not been published. The species is oviparous. Its recognition is based on...
A nice report has been posted at www.madcham.de:
Chameleons are frequently observed defecating when handled, even when the handling is non‑invasive, such as lifting an individual on a branch or stick. The behaviour is consistent across the group and appears in both field and captive contexts. Its regularity suggests that it is not an incidental accident but a stereotyped response to acute stress....
In the hills of Ambohitantely and the surrounding pockets of remnant high‑plateau forest, a spectacular chameleon remained almost unknown: a dwarf population of Calumma crypticum living above 1600 meters. These high‑elevation enclaves host individuals that differ strikingly from other populations of the species complex of C. brevicorne. They are...
In Madagascar's forest undergrowth, a spectacular tiny dragon crawls through the grass and bamboo stems — Calumma gastrotaenia, a master of disappearance.
Calumma gastrotaenia is a small, cryptic chameleon of Madagascar's eastern forests, defined by a narrow body, a delicate rostral process, and a characteristic lateral stripe. For specialists, it represents one member of a larger complex of closely related Calumma species in which many taxa differ only by tiny morphological details,...
For centuries, chameleons were treated as a textbook example of deception, believed to change color according to whatever background they touched.
Ambohitantely is a high‑plateau rainforest fragment in central Madagascar, northwest of Ankazobe, protected as a Special Reserve and known for its unique mix of humid‑forest and highland species. Its isolation has produced distinct local forms across many taxa. Among chameleons, Brookesia thieli, Calumma globifer, C. gastrotaenia, C. fallax, and C....
Madagascar is a landscape where color behaves like a living force. Its forests hold more than a hundred species of chameleons, each capable of shifting hue through structural manipulation of light. This biological phenomenon mirrors a geological one: the island is one of the world's richest sources of color‑changing gemstones. The same principle —...
Calumma parsonii is the largest chameleon species of all. Its remarkable size is their advantage and their curse at once: a giant among arboreal reptiles, yet so heavy and slow that the cold season presses on them more than on any smaller forest dweller. When the temperatures fall in the wintertime under a certain threshold, they begin to...
One of the typical antipredatory strategies of small Calumma species such as C. hofreiteri, C. fallax, C. nasutum, C. pinocchio, C. glawi, C. gastrotaenia and others is to sleep on a vine or bamboo port hanging loosely from the tree canopy down. The line can be 1, 2 but even six meters long or...
Calumma globifer is a large canopy chameleon of Madagascar's eastern rainforests, often seen astonishingly high above the ground rather than in understory vegetation. Adults and juveniles alike use height as their primary refuge, resting on exposed branches where their cryptic pattern merges with moss, lichen, and bark.
Brookesia decaryi is a leaf‑litter chameleon from the dry forests of Ankarafantsika in northwestern Madagascar, described by Angel in 1939. It was reported to climb quite high into trees, and its appearance provides perfect protection on bark.
Calumma pinocchio was described from Vohimana in the northern central east of Madagascar by Glaw, Agne, Prötzel, Gehring, Köhler, Preick, Ratsoavina, Straube, Wollenberg Valero, Crottini and Vences in 2025 (Salamandra 61(4): 442–466). Its rostral process, a sword‑like lance, is spectacular, yet it is soft; if you want to know more about its...
Furcifer bifidus shows sexual differences early in life: males develop reduced horns, while females never form horns. At night the species displays a two‑sided color pattern, with the moonlit or flashlight‑lit flank turning shiny green and the shaded flank bright yellow. In general, Furcifer bifidus is one of Madagascar's larger chameleons, notable...
Male Calumma parsonii show population‑specific eye‑turret coloration across their fragmented humid‑forest range. Each forest block produces its own stable chromatic signature in adult males:
Furcifer oustaleti in the Morondava region shows marked phenotypic variability, far exceeding what is typically reported for the species elsewhere in western Madagascar. Individuals range from uniform sandy brown to saturated green, with males displaying a distinct purple interstitial gular skin visible when the throat expands during display....
Trioceros feae is an insular chameleon restricted to Bioko, an island called also Fenrando Poo belonging to Equatorial Guinea.
Trioceros cristatus is a middle-sized, forest‑dwelling chameleon from West and Central Africa, known for the raised dorsal crest that gives the species its name.
Furcifer lateralis, the carpet chameleon, is one of Madagascar's most widespread species. It thrives in the central highlands, in gardens, bushland, eucalyptus belts, and degraded forest edges. In the warm months it is abundant, visible, and active. But when winter arrives, the species changes its entire strategy.
The climate of the central plateau...
A new study re‑evaluates the occipital‑lobed chameleons traditionally grouped as the Calumma cucullatum complex. The authors show that this phenetic assemblage is not monophyletic. Instead, the C. furcifer group is recovered as sister to C. cucullatum, while C. malthe forms the sister lineage to a clade containing the C. nasutum group and the C....
Chameleons do not bruise like mammals. They do not turn blue, purple, or yellow. They turn black. A small impact, a bite, a fall, or even firm handling can produce a jet‑black patch within minutes. This dramatic response is not cosmetic. It is physiology, and it is precise.
This article explains the mechanism behind black bruising, how to...
A hematoma is simple in principle: blood escapes from damaged vessels and pools inside tissue. The chemistry of that blood determines the colors seen in mammals. Fresh hemoglobin is red‑blue, biliverdin is green, bilirubin is yellow, and hemosiderin is brown‑black. As a mammalian bruise ages, these pigments shift, producing the familiar...
Palleon nasus is one of Madagascar's most elusive reptiles—a pygmy chameleon so inconspicuous that even seasoned herpetologists rarely encounter it. It belongs to the genus Palleon, the only Malagasy pygmy chameleon lineage with a laterally flattened body, unlike the cylindrical forms of Brookesia. This subtle flattening gives it a leaf‑like...
Nosy Be panthers are famous for "robin‑blue," but that tone is mostly a captive invention. Wild males show a far richer and more natural spectrum. Their base colors range from vivid green with clean blue strikes along the flanks to almost uniform yellow individuals, yet one feature never disappears: the red marking on the eye turrets. That ocular...
In the rainy season, Furcifer viridis from the Morondava region shows a saturated, vivid green. The flanks may carry thin blue strikes, and the dorsal surface keeps a fresh leaf‑green tone. In photographs taken during peak rains, individuals appear almost luminous against the wet understory.
The so‑called "panther of Ambato" represents a localized chromatic population of Furcifer pardalis occurring in the rural belt near Ambanja, around Ambato and its surrounding hamlets. Although geographically close to the classic Ambanja phenotype, these animals differ in several consistent traits. Males show a markedly lighter, almost translucent...
shares a small adventure with a big heart.
Péče o chameleony stojí na rozcestí. Mezi tradicí, zvykem a polovičním poznáním se zvedá nová vlna zjednodušených doktrín — hlasitých, sebevědomých a nebezpečně neúplných. Za každým živým tvorem však stojí fyziologie, která se neohýbá podle lidské pohodlnosti. Tento text je připomínkou, že skutečná odbornost se získává, nikoli deklaruje, a že...
New fieldwork from the Ivohiboro region in southeastern Madagascar adds important data to the earlier herpetofaunal study published two years ago. The protected area lies southwest of the southernmost slopes of the Andringitra Mountains. The forest itself covers about 8.6 square kilometers within a larger 37.8 square kilometer conservation zone...
