In snakes, the ventral scales or gastrosteges are the enlarged and transversely elongated scales that extend down the underside of the body from the neck to the anal scale. When counting them, the first is the anteriormost ventral scale that contacts the paraventral (lowermost) row of dorsal scales on either side. The anal scale is not counted. [1]
The shape and arrangement of scales is used to identify snake species. 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 ...
Scales in the central or throat region, which are in contact with the first ventral scales of a snake's body and are flanked by the chin shields, are called gular scales. The mental groove is a longitudinal groove on the underside of the head between the large, paired chin shields and continuing between the smaller gular scales.

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 ...

Nomenclature of scales (top view of head) Parietal scales are the scales of a snake located on the snake's head and are connected to the frontals towards the posterior. [1] These plate-like scales are analogous to and take their name from the parietal bone, which forms the roof and sides of the cranium in humans.
