Most female chameleons lay eggs. The number of eggs laid varies. When the eggs are ready to be laid, the female climbs down to the ground and digs a hole. She deposits the eggs in the hole, buries them, and leaves the nesting site. During incubation, the eggs absorb water from the earth and can gain up to 0. There are a few chameleons, such as the Jackson's chameleon, that are viviparous. A few days after the young hatch or are born, they begin to hunt insects.
They instinctively know how to survive without a parent to teach them. The hatchlings look like miniature adults, except that their coloration and markings are not as bright. They grow quickly, and many reach sexual maturity before the end of their first year. The Jackson's chameleon is native to the humid, cooler regions of Africa's Kenya and Tanzania. It is usually found in great numbers in mountainous areas. One subspecies was introduced to Hawaii in the s and has since grown into a large, feral population.
The Jackson's chameleon is a small- to medium-sized chameleon best known for its sawtooth-shaped dorsal ridge. The female Jackson's chameleon is one of the few chameleons that give live birth instead of laying eggs—from 8 to 30 live young after a 5- to 6-month gestation period. Jackson's chameleons are sometimes called three-horned chameleons because males have three brown horns the females usually have no horns. The horns are used to defend territory. On a narrow tree branch, males may lock horns and try to push the other off.
Jackson's chameleons are usually bright green, with some traces of blue and yellow, and are usually less territorial than most species of chameleons. Madagascar is home to nearly two-thirds of all chameleon species. Three of those— Belalanda chameleon Furcifer belalandaensis , bizarre-nosed chameleon Calumma hafahafa , and Namoroka leaf chameleon Brookesia bonsi —are at critical risk, losing their habitat to slash-and-burn agricultural practices, logging for construction or charcoal, and cattle grazing.
Number of young: Small chameleons lay 2 to 4 eggs, large varieties lay 80 to eggs. Those that give birth to live young produce 8 to 30 young. A chameleon's tongue can be shot out to an extraordinary length: in some types, the tongue is longer than the body. It is generally gray or brown in color with lighter patches throughout, punctuated by yellow or red stripes around the throat. It also has large dorsal spines and a prominent casque.
Males display crests and three horns. This is a fairly large species, growing to be almost a foot long. There are currently less than a dozen known populations of this species in the world, isolated to remnants of forest lands.
Continued forest degradation threatens remaining populations, and they are protected from capture or slaughter by the Cameroonian government. This species is found in Nigeria, Cameroon, Mali and, of course, Senegal. It is usually olive colored, and about 9 or so inches in length.
In this species, the female is generally larger than the male. The Tiger chameleon grows to about six inches long in adulthood and comes in an array of colors that often includes gray, orange, green, or brown. Its most distinguishing features are the grouping of spikes on its chin and the long, pointy protrusion on its chin. They usually grow to be around a foot long and have a distinctive fused occipital lobe.
Males have three annulated horns on their heads. Females have just one. Named for its horn-like nose which is especially prominent in males , this species grows to be around 11 inches long. It has a small crest on its head, as well as a crest running partway down its back.
Also known as Sahel chameleon, this variety is endemic to dry savannah areas of the Sahel in Africa. Fairly large, this chameleon species grows up to 18 inches in length.
It is usually green with an array of black spots and a large, bony casque on its head. This bluish green chameleon species is found in lowlands throughout Sub-Saharan Africa, and is distinguished by being very slender compared to many other chameleon species. Lizards from the genus Rhampolean are native to Africa and are all relatively small in size. Stump-tailed chameleons are fairly small, and have short tails in relation to the rest of their bodies.
They are often grey or brown in color. Because of their size, these types of chameleons are often wrongly believed to be pygmy chameleons. Its name comes from the way it resembles a leaf when it sits still on tree branches. Found in the rainforests and coastal lowlands of central and western Africa, this chameleon species is also quite small. Commonly known as Leaf Chameleons, species belonging to the genus Brookesia are endemic to Madagascar.
They are all fairly small, and many of the species within this genus were only discovered within the last few decades. Unfortunately the only known population is in decline due to habitat loss; these animals are condsidered endangered. One of the smallest four-legged animals in the world, this species is one of the more recently discovered among chameleons. Name for the Nosy Be Forest?? Also distinguished by their minimal size, Antongil Leaf chameleons are from northeastern Madagascar.
As a result of deforestation, populations of this species have become smaller and more fragmented. Because of this, they are considered endangered. You may see the Armored Leaf referred to as the Antsingy Leaf both are correct. This chameleon is the largest of the Brookesia genus, reaching a length of up to 11 cm.. They are brown and spiny, and can easily blend in with the leaves on the forest floors of its native It is northeastern Madagascar.
This chameleon is sometimes called the Brown Leaf chameleon. Their coloration — brown, green, dark red, olive, or combinations of these — and their high, flat bodies do make them resemble a dead leaf.
Native to eastern Madagascar, these small chameleons have impressive horns and spiny scales. The elaborate pattern and coloring usually ever-changing combinations of greens and browns leave no question about how this species got its name. Also found in eastern Madagascar, this species is very small and easily able to blend in with its densely forested habitat. While it is not endangered, there is concern about conservation of this species due to rapid loss of forest lands in Madagascar.
Like the Brookesia genus, chameleons belonging to Furcifer are mostly endemic to Madagascar. This species is distinguished by having the shortest lifespan of any four-legged vertebrate. Once it hatches, this chameleon lives for about 4 to 5 months. Unlike many other chameleon species, the female Lesser chameleon is the more colorful of the two sexes, displaying green and yellow bands along with yellow speckling. Males usually have duller coloration, often with black and white banding.
They mostly inhabit forested areas in Madagascar, but have been known to thrive elsewhere, with populations cropping up in farmlands and plantations surrounding their native habitat. Sometimes called the White-Lined chameleon, this species comes mostly from central Madagascar. Carpet chameleons are bred and sold as pets throughout North America and around the world.
Male Tusked chameleons can reach a length of 19 inches upon maturity. The pointed rostal appendages apparent on male specimens are what give this species its name. These chameleons range in color and patterning, with some displaying solid bright green coloring and others having dark bands. From northwest Madagascar, this chameleon species is usually brown or grayish and has a distinctive spike at the front of its head. Panther chameleons come in a variety of bright colors, and are one of the types of chameleon commonly bred and sold as pets.
Sometimes called Warty chameleon or Crocodile chameleon, this species has a distinctive casque and small ridges running between its eyes and snout. This is in addition to the namesake spines that run along its back. For one, they are quite large.
They reach lengths of up to two feet as adults. They also have a signature scalloped ridge on the back and a single rostral horn on the head. Expert Tip: This is the species we recommend for experienced owners who want to mix things up a bit. This chameleon has a different look than many others, making them quite fun to observe.
Panther Chameleons are colorful creatures that can take on a spectrum of vibrant hues. These lizards change their color to communicate with one another and absorb radiant heat. You might see them take on shades of turquoise, red, green, and more. Generally, males are more colorful than females. But, female Panther Chameleons can alternate between beautiful shades of pink and high-contrast tones of red or black. In most cases, the color change in females all depends on their receptiveness to breeding.
Males can reach lengths of up to 20 inches while females usually stop growing after 12 inches. Panther Chameleons are solitary animals. They can get territorial with others, so they prefer to live alone. While not particularly aggressive, excess handling could lead to unwanted stress. Some can have a single horn or sport as many as six! Either way, their horns are the most defining feature of this species.
Unlike other popular types of chameleons in the trade, this kind is more muted when it comes to color. They usually have more natural tones of red and yellow. Their scale pattern is more varied as well.
You might see some accents of purple, orange, or blue. But, most of the body is natural-looking for easy camouflage. Four-Horned Chameleons are best for reptile enthusiasts with some experience.
The reason for this is the strict demands of this species. They require very warm and humid environments like their native habitats in Cameroon. Males can reach maximum lengths of about 27 inches! Females only get about half that size, but they can still be hard for inexperienced owners to manage.
Not only do they need large enclosures, but they need a lot of humidity. This type of chameleon prefers humidity levels to be at 70 percent or higher.
They come from humid forests in Madagascar, so this preference is not surprising. Many owners shower their chameleons with warm water for an hour every week. This can help keep the lizard hydrated. These lizards need a well-planted enclosure with plenty of moisture-absorbing substrates. Regular misting and relatively warm temperatures are a must, too. Researchers classify animals, as well as plants, into a species when the population can breed to produce new offspring, and the offspring in turn goes and produces their offspring.
If the offspring of the original pair cannot produce its offspring, they cannot be considered a new species. Through natural selection, new species can and do evolve from existing ones, meaning this field is ever-evolving.
The number of species is likely to change in the future as research continues and new species could be discovered. These primary tree-dwelling lizards will vary in size, color, and appearance depending on the species, and these characteristics help differentiate these animals.
Researchers have classified four genera of true chameleons, including Bradypodian, Chamaeleo, Rhampholean, and Brookesia. There are two more genera, Calumma and Furcifer, but only some researchers recognize these additional genera. These animals are separated into different species based on several characteristics, including size, head ornamentation, and coloration. Understanding the evolution of chameleons begins by going back to the early fossils to help tell the story.
