The shape and number of scales on the head, back and belly are characteristic to family, genus and species. Scales have a nomenclature analogous to the position on the body. In "advanced" (Caenophidian) snakes, the broad belly scales and rows of dorsal scales correspond to the vertebrae, allowing scientists to count the vertebrae without ...
Procedurally generated tiling textures. In computer graphics, a procedural texture [1] is a texture created using a mathematical description (i.e. an algorithm) rather than directly stored data. The advantage of this approach is low storage cost, unlimited texture resolution and easy texture mapping. [2]
Keeled scales of a colubrid snake (banded water snake; Nerodia fasciata). In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection.
Water collection has been shown in some rattlesnakes, though the nanostructure of the scales is thought to be more significant than the macrostructure (keel) of the scales. [6] In some viperines, most notably those of the genus Echis, the lateral scales are not only keeled, but the keels have minute serrations. The snakes use this in a warning ...
Skinks' skulls are covered by substantial bony scales, usually matching up in shape and size, while overlapping. [4] Other genera, such as Neoseps, have reduced limbs and fewer than five toes on each foot. In such species, their locomotion resembles that of snakes more than that of lizards with well-developed limbs. As a general rule, the ...
The species is commonly called the common rough-scaled lizard or savanna lizard. It is largely found in southern Africa. These lizards are terrestrial and found in the range of mesic savannah. The common rough-scaled lizard is medium in size and well distributed in parts of Namibia, Botswana, Zimbabwe, Angola, Tanzania, and Zambia. [1]
Domestic cat or house cat (Felis catus) [3] Common North African wildcat (Felis lybica lybica) [27] 8000–7500 BCE [27] the Near East: meat, pelts, pest control, research, show, pets Tame, slight physical changes Very abundant in captivity; true wildcat species less abundant, though not rare, feral populations very common 1c Carnivora
Scales mostly consist of hard beta keratins which are basically transparent. The colours of the scale are due to pigments in the inner layers of the skin and not due to the scale material itself. Scales are hued for all colours in this manner except for blue and green. Blue is caused by the ultrastructure of the scales. By itself, such a scale ...
