The common chameleon or Mediterranean chameleon (Chamaeleo chamaeleon) is a species of chameleon native to the Mediterranean Basin and parts surrounding the Red Sea. It is the only extant species of Chamaleonidae with a range that naturally extends into Europe.
Four subspecies are currently recognized:
The average length of the common chameleon is 20–40 cm (8–16 inches), with females often being substantially larger than males. The colour of the common chameleon is variable, between yellow/brown through green to a dark brown. Whatever the background colour is, the common chameleon will have two light coloured lines along its side. It has a small beard of scales and some small hard scales on the top of its back. Many assume the color changes undergone by the chameleon are a result of its attempting to camouflage itself, when in reality the chameleon changes its color as a response to light and temperature stimuli and as an expression of its emotions (like chameleon body language). Often when caught for analysis, the chameleon may turn a dark color. Their colors are also important for intraspecies communication, especially during the mating season. [2]
The common chameleon is insectivorous, capturing insects by stealth and the rapid extension of its long tongue, which has a terminal pad which grasps and adheres to the prey. Common prey items include flies (Diptera), hymenopterans (Hymenoptera), true bugs (Heteroptera), crickets and grasshoppers (Orthoptera), and beetles (Coleoptera). [3] Adults are known to eat young chameleons and have been observed to eat fruit. [2]
The common chameleon like others of its family enjoys an arboreal habitat, scrambling about in trees and bushes with feet that have five toes, in groups of two or three on each side for grasping branches. It also uses its prehensile tail to maintain balance and stability. Movement is usually leisurely, often with a slight swaying motion to avoid detection by predators. The animal can move more rapidly when involved in a territorial dispute. [2]
The common chameleon is usually solitary, maintaining a territory and only tolerating members of the opposite sex during the mating season. It is sexually mature within one year and the females produce one clutch of eggs per year. Larger females produce more eggs and are more attracted to males who will fight over a female. The mating season for the common chameleon is from mid-July to mid-September. The animals descend to lowers levels of vegetation or to the ground to search for a mate. The eggs are laid in the soil and take from 10–12 months to incubate. Adult animals, especially males, will eat young that they encounter. [2]
In Europe, it is only autochthonous to: southern Portugal, [4] [5] southern Spain, southern Italy, Cyprus and the Greek island of Crete. Nevertheless, it has been successfully introduced into other Greek islands, Canary islands and Malta. In Malta, Jesuit priests are thought to have introduced this species around 1880 in a small private garden in St. Julian's. [6] Since then, this species seems to have flourished and spread across the island, with sightings being reported in Gozo, Malta's sister island. [7] A small population is reported to be present in Apulia and Calabria in southern Italy.
In North Africa and the Middle East, it occurs in Morocco, Algeria, Tunisia, Libya, Egypt, [8] Israel, Palestine, Jordan, Western Sahara, Saudi Arabia, Yemen, Turkey, Lebanon, Syria, Iraq, and Iran. In Greece, the species is now only found on the island of Samos, having disappeared from the other islands in recent years. Conservation efforts on Samos are being led by the Archipelagos Institute of Marine Conservation to preserve the remaining populations, but the species is not currently evaluated under the IUCN redlist. [9]
While the species is common throughout most of its range, it is threatened locally by habitat loss, principally through urban development, the intensification of agriculture, predation by domestic animals, illegal collection for the pet trade, and roadkill mortality. Wildfires constitute a threat in Turkey. [1]
Chameleons or chamaeleons are a distinctive and highly specialized clade of Old World lizards with 200 species described as of June 2015. The members of this family are best known for their distinct range of colours, being capable of colour-shifting camouflage. The large number of species in the family exhibit considerable variability in their capacity to change colour. For some, it is more of a shift of brightness ; for others, a plethora of colour-combinations can be seen.
The veiled chameleon is a species of chameleon native to the Arabian Peninsula in Yemen and Saudi Arabia. Other common names include cone-head chameleon, Yemen chameleon, and Yemeni chameleon. They are born pastel green and without their distinctive casques on their head.
Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas. A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.
The Greek tortoise, also known commonly as the spur-thighed tortoise or Moorish tortoise, is a species of tortoise in the family Testudinidae. Testudo graeca is one of five species of Mediterranean tortoises. The other four species are Hermann's tortoise, the Egyptian tortoise, the marginated tortoise, and the Russian tortoise. The Greek tortoise is a very long-lived animal, achieving a lifespan upwards of 125 years, with some unverified reports up to 200 years. It has the largest known genome of all reptiles.
Jackson's chameleon, also known commonly as Jackson's horned chameleon, the three-horned chameleon, and the Kikuyu three-horned chameleon, is a species of chameleon, a lizard in the family Chamaeleonidae. The species is native to East Africa, and introduced to Hawaii, Florida, and California. There are three recognized subspecies.
The Namaqua chameleon is a ground-living lizard found in the western desert regions of Namibia, South Africa and southern Angola.
The panther chameleon is a species of chameleon found in the eastern and northern parts of Madagascar in a tropical forest biome. Additionally, it has been introduced to Réunion and Mauritius, as well as the state of Florida within the United States.
The Indian chameleon is a species of chameleon found in Sri Lanka, India, Pakistan and select other parts of South Asia. Like other chameleons, this species moves slowly with a bobbing or swaying movement and are usually arboreal. They have an extremely long and sticky tongue, which they use to catch insects from several feet away. Also like other chameleons, C. zeylanicus has bifurcated feet with a tongs-like shape, a prehensile tail, independent eye movement, and the ability to rapidly change skin colouring and patterns. Despite common misconceptions, they do not change their visual appearance based on their surroundings or background, or even for camouflage, and may not even be able to perceive colour differences; rather, it is primarily for communication with others of their species, including to signify the receptiveness of a female or submissiveness in general disputes. Additionally, colouring can change for controlling body temperature, changing to darker colours to absorb heat, or lighter to cool themselves.
Parson's chameleon is a species of chameleon in the family Chamaeleonidae that is endemic to eastern and northern Madagascar. It is found from lowlands to an altitude of 1,195 m (3,920 ft) above sea level and mainly inhabits humid primary forest, but can also occur in disturbed habitats with trees. For a chameleon, it is very large, long-lived and slow-reproducing.
Trioceros melleri, with the common names Meller's chameleon and giant one-horned chameleon, is the largest species of chameleon from the African mainland.

Furcifer balteatus, also known as the two-banded chameleon or the rainforest chameleon, is a species of chameleon that is endemic to Madagascar. It was described by André Marie Constant Duméril and Gabriel Bibron in 1851.
The Antimena chameleon is a species of chameleon that is endemic to southwest Madagascar. It was initially described by French naturalist Alfred Grandidier in 1872.
The crested chameleon, also known as the sail backed chameleon, is a species of chameleon native to forests and semi-open wooded habitats in Central Africa.
