A Rare Hatching! Canvas Welcomes Baby Jeweled Chameleons

While every successful birth is a wonder to behold, Canvas Chameleons had the opportunity to welcome a fairly rare event at the beginning of the month: the hatching of a few Jeweled Chameleons (Furcifer Campani). This is only our fourth line of unrelated captive births of these wondrous creatures. So, in celebration, we thought it was appropriate to bring additional information to our readers about this unique event.

Getting to Know Furcifer Campani

Furcifer Campani, also known as the Jeweled Chameleon, is a native to the country of Madagascar, living within an approximately 5,600 square mile section from Ankaratra to the Andringitra National Park. Traditionally, these chameleons are fairly small. At birth, they are often a bit less than an inch long and only reach around 5.5 inches in length once full grown. They also feature distinct coloring and markings that make it fairly unique within the chameleon family.

Most Jeweled Chameleons vary in color from a pale green to a dark brown, with three well-defined lighter bands running along the length of the body. Along with the bands, these chameleons feature numerous light-colored spots across the body and, in some cases, a section of red spots on the head.

The successful hatching of Jeweled Chameleons is a rare event in captivity. Part of the reason for the rarity is the fact that the export of these chameleons from Madagascar is no longer permitted, so not many breeders have the opportunity of enjoying the company of a Jeweled Chameleon, let alone the chance to witness a successful birth. Additionally, the incubation period can reach around nine months, which is a long period of time for maintaining the ideal conditions required for the young to be born.

Status of Jeweled Chameleons in the Wild

At this time, the Jeweled Chameleon is considered vulnerable as a species based on the IUCN Red List of Threatened Species. This is partially due to the fragmented nature of the population as well as the decline in the quality of their habitat. Much of the area where these chameleons are found naturally is subject to slash-and-burn agriculture, causing some habitat to be lost to the associated damage while the rest is lost to development.

Additionally, the population is still considered to be decreasing. This means it risk level could change in the future should the number of Jeweled Chameleons in the wild continue to decline.

With that in mind, we are honored to be able to bring information about this magnificent species to our visitors and hope you get a chance to appreciate one of the newest additions as shown in the video here.






Here Today, Gone Tomorrow | The Endangered Belalanda Chameleon

Native to the south-western portion of Madagascar, the Belalanda Chameleon, or Furcifer belalandaensis, is considered to be a critically endangered species. The International Union for Conservation of Nature (IUCN) includes the Belalanda Chameleon on their Red List, which contains a variety of species that are thought to be on the edge of extinction.

What Does Critically Endangered Mean?

The IUCN develops criteria to help classify the health of animal species across the world. If classified as critically endangered, it is believed that the species faces an extremely high risk of becoming extinct in the wild. The Belalanda Chameleon is considered critically endangered due to the limited size of its known natural habitat, as well as the assumed size of the population.

A Tiny Natural Habitat

The Belalanda Chameleon is named after the town of Belalanda, where this particular species can be found. While many chameleons inhabit Madagascar, the Belalanda is thought to only live in an area of about 1.5 square miles. Much of the gallery forest that was known to be home to this particular chameleon has been cleared away, but reforestation efforts, combined with education of the local population, aim to help bring this species back from the brink.

A Mysterious Creature

One of the only descriptions that is fairly easy to find is that the Belalanda Chameleon is green in color. Due to the falling population, not much else is known about the Belalanda Chameleon. This makes conservation efforts particularly challenging, as it is difficult to determine what kind of environment would help the population reestablish itself in its home area. With that in mind, funding had been provided to help the Durrell Institute for Conservation and Ecology in the United Kingdom, and Madagaskiara Voakajy of Madagascar to study the species and its habitat to help draw plans for further protection.

Protection Efforts

In order to support protection efforts, the Belalanda Chameleon cannot be collected, transported, or traded away from the local area. As part of the conservation efforts, the species will be evaluated to determine if it is suitable for captive breeding, which may help increase the wild population while also allowing some to be housed in appropriate facilities.

So far, the Belalanda has only been found in three towns in Madagascar, and the true number that exist in the wild is still unknown.














A Dwarf and a Giant: Chameleons’ Extreme Size Diversity

Chameleons come in a rainbow of colors with a variety of features and in a variety of sizes; however the size difference between the largest and smallest chameleon is extreme — one is the size of a small house cat and the other fits comfortably on the tip of your thumb. The extreme variation in size is a wonderful example of how diverse chameleons can be.

Smallest chameleon: Brookesia micra

Brookesia micra is the world’s smallest chameleon; it is also the tiniest lizard that has been discovered thus far. It was discovered on Nosy Hara, a tiny island off Madagascar, in 2012. Adults grow only about 1.1 inches in length (small enough to rest on the head of a matchstick). These chameleons may be effected by “island dwarfism,” a phenomenon in which a species adapts over time to its restricted habitat by becoming smaller. Dwarf chameleons originally evolved on Madagascar, thus Brookesia micra chameleons may be exhibiting an extreme case of island dwarfism considering their close proximity to Madagascar. Brookesia micra chameleons typically live in leaf litter during the day as they forage for food, but they climb out onto limbs at night for protection and do not move once they find their spot.

Brookesia micra chameleons are light gray on the head, back, and tail with the tail becoming an orange and then a yellow color near its tip. The sides of the chameleons are brown.

Largest: Parson’s chameleon

Parson’s chameleons are thought to be the largest chameleons in the world; they live in the central eastern forest regions of Madagascar. These chameleons can grow up to 27 or 28 inches in length throughout their lifetime and weigh one to two pounds. Yes, you read that Parsoni Male 1 - Canvas Chameleons Small (1)correctly – “throughout their lifetime.” Unlike most other animals, chameleons never stop growing throughout their lifetime; they simply shed their skin when they outgrow it. Parson’s chameleons have a lifespan of more than 6 years. A parson’s chameleon’s tongue can be as much as twice the length of its body.

Parson’s chameleons have ridges that run from above their eyes to their nose, forming two warty horns. They can vary in color from green to turquoise to yellow; the Calumma parsonii cristifer subspecies is typically bluer and smaller than the Calumma parsonii parsonii subspecies.
These chameleons represent just one example of the stunning diversity of chameleons. What are some of your favorite examples of chameleon diversity?

Two New Discoveries Expand the Chameleon Family

Chameleons belong to a diverse family. The longest chameleon can grow to approximately two feet in length while the smallestwelcome to canvas chameleons chameleon can fit on the tip of your thumb. Chameleons range in color from brown and green hues to white and bright blues, greens, yellows, and reds.  Two recent discoveries have expanded the family’s diversity.

Oldest chameleon?

100 million years ago, a small lizard creature was crawling through the tropics of present-day Myanmar when it had the misfortune of getting trapped in the resin of a coniferous tree. This resin, which fossilized into amber, preserved the dime-sized specimen along with 10 other specimens of lizards. That means these specimens became fossilized during the Dinosaur Age.

These specimens were made available for study by a private collector at the American Museum of Natural History. A team led by Edward Stanley, a University of Florida postdoctoral student in herpetology at the Florida Museum of Natural history, used 3D scanning techniques to examine the specimens. One specimen had chameleon-like characteristics that lead researchers to believe it is a chameleon; for example, the specimen has the chameleon’s projectile tongue but had not yet developed the body shape and toes we currently associate with chameleons.

These specimens will be studied more closely and will be named in the future. If this specimen is a chameleon, it will be approximately 78 million years older than the previously thought oldest chameleon making it the oldest chameleon on records.

Stay tuned for more developments on this!

New species 

In the same year scientists discovered what is possibly the oldest species of chameleon, they also discovered a new species of chameleon in Tanzania. The new species is named Kinyongia msuyae, in honor of Tanzania herpetology pioneer Charles A. Msuyae. According to the Wildlife Conservation Society, “The brown and green chameleon with scattered blue spots was found in four montane forest patches in the Udzungwa Mountains and Southern Highlands.”

While discovering new species is always exciting, this discovery also provides insight into the biodiversity of the Makambako Gao, which is a disputed “zoological barrier” between regions of the Southern Highlands and Eastern Arc Mountains. The presence of this chameleon lends credence to the argument that this barrier does not exist and that there is a close relationship between the biodiversity of the neighboring regions.

What are your thoughts on these discoveries?




Rhampholeon acuminatus – Nguru Pygmy Chameleon

I think this series of pictures is by far one of my all time favorites! Baby #3 was being extremely shy and didn’t want to come out in full view of the camera. She was perfectly fine with hiding behind my finger as much as possible.

Please help us spread these photographs by sharing them on your page. The more attention and awareness we can bring to these incredible R. acuminatus pygmy chameleons the better!

Round two of these amazing and so tiny R. acuminatus baby chameleons. This little guy is sporting an extra large rostral right out of the egg. I’m not positive but I would be willing to bet this guy is a male because of that.

A little information for those who are not familiar with this species, Rhampholeon Acuminatus are endemic to the Nguru Mountains in Tanzania. This is how they received their common name of the Nguru pygmy chameleon.

Rhampholeon acuminatus – Nguru Pygmy Chameleon

Great things always come in small packages! We just had our last clutch of eggs hatch from our Rhampholeon acuminatus group. It is bitter sweet as these little gems will most likely be the last of the acuminatus that we will have here at Canvas. So, we decided that we will post pictures of the babies over the next few days in hope that everyone can enjoy for as long as possible!

For those of you who are not aware, as of last year R. acuminatus have been reevaluated and are now listed as “Critically Endangered” on the IUCN Red List. This is only one step up from Extinct in the wild! Because of this, we feel it is best to no longer work with this species in captivity as wild caught animals would be necessary for future breeding. Although there are currently no regulation to protect the export of R. acuminatus at this time, we hope that in the near future there will be new quotas adopted that help protect these amazing animals in the wild.

The Colorful Language of Chameleons

Chameleons communicate with color change, hunt with lightning-fast tongues—and live in some of Earth’s most threatened habitats.

By Patricia Edmonds
Photographs by Christian Ziegler

For sheer breadth of freakish anatomical features, the chameleon has few rivals. A tongue far longer than its body, shooting out to snatch insects in a fraction of a second. Telescopic-vision eyes that swivel independently in domed turrets. Feet with toes fused into mitten-like pincers. Horns sprouting from brow and snout. Knobbly nasal ornaments. A skin flap circling the neck like a lace ruff on an Elizabethan noble.

Of all its corporeal quirks, the chameleon is most defined by one, noted as far back as Aristotle: color-changing skin. It’s a popular myth that chameleons take on the color of what they touch. Though some color changes do help them blend into their surroundings, the skin’s changing hue is in fact a physiological reaction that’s mostly for communication. It’s the lizard using colorful language, expressing itself about things that affect it: courtship, competition, environmental stress.

At least that’s the belief today. “Even though chameleons have attracted attention for centuries, there’s still a lot of mystery surrounding them,” says Christopher Anderson, a biology postdoctoral associate at Brown University and a chameleon expert. “We’re still piecing together how their mechanisms actually work,” from the explosive projection of the tongue to the physics of the varying skin colors. (Learn more about chameleons at a website Anderson runs.)

“Even though chameleons have attracted attention for centuries, there’s still a lot of mystery surrounding them.”

Scientists recently have made important discoveries about chameleon physiology by watching the lizards in captivity. Their future in the wild, meanwhile, is far from certain.

When the International Union for Conservation of Nature (IUCN) released a new Red List assessment of chameleons last November, it ranked at least half the species as threatened or near threatened. Anderson is a member of the IUCN Chameleon Specialist Group, as is biologist Krystal Tolley, a National Geographic grantee whose expeditions in southern Africa have documented new chameleon species and vanishing habitats. (Read Tolley’s blog posts from her expeditions.)

In Afrikaans, says Tolley, chameleons have two common names. One isverkleurmannetjies, which means “colorful little men.” The other, trapsuutjies, translates as “treading carefully.” That refers to the lizards’ odd, slow gait—but also could be read as a plea to conserve the curious species and their home terrain.

Rostral protuberances—such as this one on a long-nosed chameleon—help individuals of like species identify each other and can be used as jousting weapons.

How Chameleons Change Color

About 40 percent of the 200-plus known chameleon species are found on the island of Madagascar. Most of the rest live on the African continent. Thanks to DNA testing, some chameleons that look nearly identical have been found to be genetically distinct. More than 20 percent of the known species have been identified in just the past 15 years.

Given their many odd traits, chameleons “have always intrigued naturalists,” Anderson says. Because the lizards often died on the journey from Madagascar and the African continent to Western laboratories, early herpetologists could only guess at how live chameleons worked. That yielded theories that seem laughable now, he says: “It was once thought that the chameleon tongue projected because it inflated with air or filled with blood, like erectile tissue.”

“It was once thought that the chameleon tongue projected because it inflated with air or filled with blood, like erectile tissue.”

Christopher Anderson

Anderson studies chameleon feeding in intricate detail. Using a camera that captures 3,000 frames a second, he turned 0.56 seconds of a chameleon eating a cricket into a 28-second instructional video on projection mechanics. (See videos of chameleon tongue projections.)

Stored in the lizard’s throat pouch is a tongue bone surrounded by sheaths of elastic, collagenous tissue inside a tubular accelerator muscle. When the chameleon spies an insect, it protrudes its tongue from its mouth, and the muscle contracts, squeezing the sheaths, which shoot out as if spring-loaded. The tongue tip is shaped so that it acts like a wet suction cup, grabbing the prey. The tongue recoils; dinner is served.

Scientists have more to learn about tongue projection, Anderson says. His research suggests that in some chameleons, it may go even farther and faster than previously thought.

The understanding of chameleon coloration also has changed over time—and dramatically earlier this year, when Michel Milinkovitch’s research was published. Scientists had long thought that chameleons changed color when skin cell pigments spread out along veinlike cell extensions. Milinkovitch, an evolutionary geneticist and biophysicist, says that theory didn’t wash, because there are many green chameleons but no green pigments in their skin cells.

So Milinkovitch and his University of Geneva colleagues began “doing physics and biology together,” he says. Beneath a layer of pigmentary skin cells, they found another layer of skin cells containing nanoscale crystals arranged in a triangular lattice.

By exposing samples of chameleon skin to pressure and chemicals, the researchers discovered that these crystals can be “tuned” to alter the spacing between them. That in turn affects the color of light that the lattice of crystals reflects. As the distance between the crystals increases, the reflected colors shift from blue to green to yellow to orange to red—a kaleidoscopic display that’s common among some panther chameleons as they progress from relaxed to agitated or amorous. (See a video Milinkovitch’s team made of a panther chameleon color change.)

New Ways to Hide

At age seven, Nick Henn got his first chameleon. Twenty years later the hobbyist and breeder keeps as many as 200 of them in the basement of his business in Reading, Pennsylvania.

Rows of wire-mesh cages contain plants for climbing and sandy floors where females can lay eggs. Lights and misters simulate the lizards’ native climes. Arranging the cages is as tricky as seating warring factions at a United Nations summit. To keep the animals from riling each other, Henn places females where they can’t see males, and males where they can’t see females—or rival males.

Ember, a young male panther chameleon, is a so-called red bar, a variety that’s native to the Ambilobe district in northern Madagascar. His torso has red and green zebra stripes plus an aqua blue racing stripe along each side. When Henn opens Ember’s cage and prods him to climb onto a long stick, he “gets grumpy,” which Henn knows because the chameleon’s red bars get a little brighter.

Henn carries Ember on the stick around a corner to the cage inhabited by Bolt, an adult male blue-bar panther chameleon and the largest lizard in Henn’s collection. When Henn opens the door, and Bolt sees Ember, the response is immediate. By the time Bolt has advanced a few inches, his green bands have turned vivid yellow, and his eye sockets, throat, and spiked spine have changed from green to red orange. Ember becomes redder—but as shows go, Bolt’s is far more flamboyant. For good measure, as Bolt crawls nearer, his mouth gapes wide, displaying bright yellow gums.

“I keep envisioning the little chameleons clinging to their branches as that forest is getting chopped.”

Krystal Tolley | biologist and National Geographic grantee

Henn retreats and puts Ember back in his cage. Had he not, he says, Bolt might have tried to ram or bite Ember, whose skin almost certainly would have changed to brown—the color of crying uncle. (A 2014 study concluded that chameleons developed this fade-to-drab submissive ability because their “slow-moving lifestyle severely restricts their ability to rapidly and safely flee from dominant individuals.”)

Though all chameleons change color, some species don’t change dramatically enough to cow observers. However, almost all chameleons do have another technique for physical intimidation: They can make themselves look larger. They narrow the width and increase the height of their bodies by unfolding their jointed, V-shaped ribs to elevate their spine. They also can look more massive by coiling their tails tightly and using their tongue apparatus to expand their throats. Turning this profile to its nemesis, the lizard looks significantly bulkier.

In the cages where Henn keeps female chameleons, one named Katy Perry—salmon pink because she’s ready to mate—is next door to one named Peanut, pink with dark bars because she has already mated and is gravid, carrying eggs. If Katy were approached by a male that impressed her with his courtship colors and bobbing, swaying dance, she might submit to being mounted. If the same male approached Peanut, she would become intensely darker with bright spots and open her maw menacingly at him. If he persisted, she’d hiss or try to bite him.

Both male and female chameleons are polygamous. Most species are egg layers, but some deliver live young in clear, cocoon-like sacs. Chameleons do no parenting, so the young are on their own as soon as they’re born or hatched.

To avoid the birds and snakes that hunt them, chameleons have evolved novel ways to hide. Most species are arboreal; when they narrow their bodies, they’re slender enough to hide on the opposite side of a branch. If ground dwelling chameleons see a predator, Tolley says, some “play leaf,” contorting their bodies to look like crumpled leaves on the forest floor.

Chameleons can hide from some threats but not from the slash-and-burn agriculture destroying their habitats. The IUCN lists nine species as critically endangered, 37 as endangered, 20 as vulnerable, and 35 as near threatened.

The entire life cycle of the Labord’s chameleon lasts roughly a year. Some chameleon species may live a dozen years in captivity, but less than half that in the wild.

Identifying New Species

Tolley and her team have identified 11 new chameleon species since 2006, in South Africa, Mozambique, Tanzania, and the Democratic Republic of the Congo. The Massachusetts-born professor has studied the lizards in Africa since 2001 and works for the South African National Biodiversity Institute in Cape Town.

When a genetics study confirms that a chameleon is a new species, “it feels like you’re not just writing some random scientific paper that nobody will read,” Tolley says. “You’re accomplishing something—this is going to be forever.”

In the next breath she notes that “at the same time as thinking, ‘Wow, this is so cool,’ it was awful. I keep envisioning the little chameleons clinging to their branches as that forest is getting chopped.”

Describing it, her voice breaks. “I could not help thinking, I wish we’d never found them,” she says. “Because if this doesn’t stop, they’ll soon be extinct.”
