While reptile scales use a sophisticated naming system (see figures), there has been a certain confusion because of synonymous names. For instance, the ventral scales are often called ventrals but gastrosteges is common in the older literature. In more recent publications they are often abbreviated as VSR (for ventral scale rows) or simply V. [4]
Reptile scale types include: cycloid, granular (which appear bumpy), and keeled (which have a center ridge). Scales usually vary in size, the stouter, larger scales cover parts that are often exposed to physical stress (usually the feet, tail and head), while scales are small around the joints for flexibility.
Snakes, like other reptiles, have skin covered in scales. [1] Snakes are entirely covered with scales or scutes of various shapes and sizes, known as snakeskin as a whole. A scale protects the body of the snake, aids it in locomotion, allows moisture to be retained within, alters the surface characteristics such as roughness to aid in ...
Exposed parts of reptiles are protected by scales or scutes, sometimes with a bony base , forming armor. In lepidosaurs, such as lizards and snakes, the whole skin is covered in overlapping epidermal scales. Such scales were once thought to be typical of the class Reptilia as a whole, but are now known to occur only in lepidosaurs.
Keeled scales on a colubrid snake, Amphiesma stolatum. Keeled scales refer to reptile scales that, rather than being smooth, have a ridge down the center that may or may not extend to the tip of the scale, [1] making them rough to the touch.
