The Namaqua chameleon (Chamaeleo namaquensis) is a ground-living lizard found in the western desert regions of Namibia, South Africa and southern Angola.
In the furthest eastern edge of its range, in eastern Namibia, it overlaps with the natural range of its relative, the flap-necked chameleon. [3], Although capable of changing colour, this chameleon is usually some shade of grey or brown with several lighter patches on the flank, dark patches below the dorsal ridge and yellow or red striping on the throat. In an experiment, dyed water placed on the side of its body visibly moved to its back and towards the head and tail. Other common names include cone-head chameleon and Yemen chameleon.

Eggs have a gestation period of 35-45 days inside the mother, and take about 100 days to hatch after being laid. All other genera of the subfamily Chamaeleoninae (Bradypodion, Calumma, Furcifer, Kinyongia, Nadzikambia, and Trioceros) have at some point been included in the genus Chamaeleo, but are now regarded as separate genera by virtually all authorities. Panther chameleons have very long tongues (sometimes longer than their own body length) which they are capable of rapidly extending out of the mouth. Space satellites are under such conditions where liquid lubrication is useless as many liquid lubricants become prone to volatilization due to extremely low pressures - from nearly 100 kPa at launch, to 10 nPa in orbit.
Chameleons Lifespan : The chameleon pet species, like Jackson, panther and veiled chameleons often survive for 5 to 10 years in captivity. Chamaeleo is a genus of chameleons in the family Chamaeleonidae. [3], This species also regularly consumes plant matter in the wild, and is one of several chameleon species recorded doing so. Although temperature varies throughout the year, the natural habitat of this species has a yearly average coastal temperature of 19.3C in the air, and 26.6-31.8C on the substrate surface. The average territory size of females is 868m² amongst inland and 382m² amongst coastal populations. Namaqua chameleons are preyed upon by jackals, hawks, and eagles, and possibly monitor lizards.
Additionally, as a reptile, its rate of loss of water is far lower than in mammals and can also obtain relatively more water from the protein degradation of food. Such behaviour may indicate a level of parental care of eggs due to the close proximity of the eggs to the parent throughout incubation. They mostly hunt their prey in sandy dunes and rocky areas[5], but some coastal populations also forage for marine arthropods in intertidal zones, making it the only chameleon species to do so. Individuals in the wild are usually found gorged to the limit; an adult has an average of 12 meals a day, each meal usually consisting of about 19-23 large darkling beetles. [5] Like most desert animals, it is adapted to high environmental temperatures, but can also tolerate periods of low temperatures. Nevertheless, females hold far smaller territories than males.
They will occasionally feed on lizards (including young chameleons of their own species), snakes, and various other arthropods. Unusually for a chameleon, they will also chase down prey attempting to flee and will sometimes seize them with their jaws rather than with their tongue.
Meller's chameleon gets its common name and specific name from a "Dr. Meller" who is mentioned by biologist and taxon authority John Gray in the section about the habitat of the species in his 1865 description. Before the use of nano films (coatings), the films used to provide the beneficiary aspects of the coating would break down easier and faster due to consistent wear and tear.
Chameleon coating is supposed to resolve the issues with fluid hydraulics where atmospheric pressure changes under different environments. Within its natural range, it inhabits arid and semi-arid areas, such as Karoo shrubland, sandy desert and gravel plains, even foraging in intertidal zones. [4] Like many chameleons, this species has nasal salt glands which excretes excess minerals such as sodium chloride and potassium. When the frontier changes from atmosphere to orbit, temperatures can range from -150 °C to nearly 200 °C[4] many of these lubrications break down at accelerated rates and thus become useless. [3][1], Unlike the arboreal chameleons of the genus Chamaeleo, its tail is not prehensile, but otherwise it still hunts in the same way, slowly stalking its prey and catching it with its long tongue. Furthermore, little storage space for water is available in the gut as it is typically filled with food.
[2]
But in the wild they have shorter lives. The purpose of chameleon coating is to provide optimal performance of material in any environment. Like some iguanids, only recently ovulated females are receptive to mating. Most species of the genus Chamaeleo are found in sub-Saharan Africa, but a few species are also present in northern Africa, southern Europe, and southern Asia east to India and Sri Lanka.
During such conflicts, individuals often severely injure each other. Description. [5][3] Similar to other chameleon species in areas near human habitation, it falls victim to introduced predators such as domestic cats, dogs and foxes.
Sometimes an extension of their resting burrow may be excavated for egg laying.
Sometimes they will take advantage of abandoned rodent burrows, but will often excavate their own as well. http://www.chameleoninfo.com/Species_Profiles.html, https://en.wikipedia.org/w/index.php?title=Chamaeleo&oldid=946497716, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 March 2020, at 15:08.
Using a lattice matrix (a template for the coating using the basket weave design), nano engineers are able to utilize properties of the diamond-like carbons and pure metals to make chameleon coatings more adaptable at even more varied environments.[3]. As a result, captive individuals do not grow as fast as they do in the wild. Chameleons are a family of lizards.Most can change the colour of their skins for camouflage, or to signal mood to other chameleons..
14 species are recognized as being valid, and subspecies are recognized for some species.[2].

Females subsequently eat as much as the stomach capacity allows.
Description. Almost all species have a maximum snout-vent length (SVL) between 15 and 40 centimetres (5.9 and 15.7 in). The tongue extends at around 26 body lengths per second.
