The "Dr. Meller" to whom Gray dedicated this species was botanist Charles James Meller (1836-1869) who worked in the area that is now Malawi.
[3], Due to the especially advanced state of embryos and eggs by the time they are laid, it has been suggested that this species is in the process of evolving ovoviviparity. 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.
Chameleon coatings are also often used on hypersonic and reusable launch vehicles that require lubrication in ambient atmosphere, vacuum (space), and during re-entry (high temperature). [3], While territories cannot be held in captivity, they are known to defend resting and nesting areas of about 35cm in diameter in captive settings.
The chameleon then turned its head and drank the water that collected on its body.
Unusually in captive settings, other chameleons of either sex may assist in covering the hole after laying. Chameleon coating is supposed to resolve the issues with fluid hydraulics where atmospheric pressure changes under different environments. Territorial conflicts when territories overlap are common.
However, this species must have a regular source of drinking water other than its food and humidity in order to survive. The idea is that when a sudden change in the environment occurs the particular nano coating will change its chemical properties to better suit itself in the environment in order to avoid wear due to friction and abrasion. On the earth the air is humid, and temperature varies only slightly in comparison to other environments like space. 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. [2] The genus Chamaeleo includes only oviparous species. A possible nano film that could be used to counteract temperature changes are the pure metals Ag (silver) and Au (gold). However, they can also drink water through capillary action; small channels in the scales can transport water across the body.
Sometimes an extension of their resting burrow may be excavated for egg laying.
Almost all species have a maximum snout-vent length (SVL) between 15 and 40 centimetres (5.9 and 15.7 in). The oldest described chameleon is Anqingosaurus brevicephalus from the Middle Paleocene (about 58.7–61.7 mya) of China.
In the wild, a 20-25cm deep burrow is excavated, and the eggs are laid in the burrow at a depth of 15cm to reach the damp layer of sand. The use of the nano thin films helped control dislocating formation of the film and helped reduce the shear rate (rate at which the film deteriorated) due to abrasion and wear several folds over. [3], Laying is taxing on females and depletes their fat reserves. The use of diamond-like carbon for short is generally one of the nano films used to inhibit abrasion. [3], Namaqua chameleons are preyed upon by jackals, hawks, and eagles, and possibly monitor lizards. 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. 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.
