Scale patterns help to indicate the species and from the references, it can be verified if the snake species is known to be venomous or not. Species identification using scales requires a fair degree of knowledge about snakes, their taxonomy, snake-scale nomenclature as well as familiarity with and access to scientific literature.
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 monocled cobra has 25 to 31 scales on the neck, 19 to 21 on the body, and 17 or 15 on the front of the vent. It has 164 to 197 ventral scales and 43 to 58 subcaudal scales. [9] It typically has more than one cuneate scale on each side. The shape of the frontal scale is short and square.
Four or five scale rows separate the suboculars and the supralabials, with 13–18 supralabials and 16–22 sublabials. [5] The fangs may reach a length of 55 mm (2.2 in), [4] the longest of any venomous snake. [5] Midbody, the 28–46 dorsal scale rows are strongly keeled except for the outer rows on each side. The lateral scales are slightly ...

Scales on the head often form a black V or W pattern. [6] Western brown snakes can be confused with the Eastern brown snake which has a pink mouth lining, [4] the Northern brown snake has a purplish/blue-black mouth lining.
