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 ...
The number and arrangement of scales on a snake's body are key elements of identification to species level. [29] The king brown snake has 17 rows of dorsal scales at mid-body, 185 to 225 ventral scales, 50 to 75 subcaudal scales (all undivided, or anterior ones undivided and posterior divided, or all divided), and a divided anal scale. [27]
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]
