Four subspecies are currently recognized:

Description

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]

Ecology

Diet

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]

Behaviour

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]

Reproduction

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]

Distribution

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]

Conservation and threats

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.

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.

<span class="mw-page-title-main">Indian chameleon</span> Species of lizard

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.
