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]
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.
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 ...
Ventral scales number 140 to 190, subcaudals 35 to 65, mid-body in 17 or 19 rows and the anal scale is single. Western tiger snake near a farm dam in Mount Barker, Western Australia. The western tiger snake head is distinct from its robust body, and grows to 2 m (6 ft 7 in) in length. Dorsally, it is steel-blue to black in color with bright ...

This species has a scale situated between the two scales whereas other species of this genus have the preocular and nasal scale in contact. [2] The Narrow-banded burrowing snake has cream to white coloured ventral scales, of which there are 140-175, and 15-30 subcaudal scales of which are divided. [2] The anal scale is also divided. [2]
This internasal pair is either present or absent in species of Vermicella; (2) Number of black bands on the body and tail combined; (3) Number of ventral scales. The ventral scales are elongated, horizontal scales that occur on the belly of the snake up until the anal plate. After the anal plate, the scales are subcaudal scales. [3]
Its most defining characteristic is its iridescent, highly polished scales that give this snake its common name (sunbeam snake). The dorsal scales a layer of dark (indigo-brown) pigmentation just below the surface on each scale that enhances the iridescence. The ventral scales are greyish-white.
