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.

The scales reflect a blue shimmer (pictured right). Illustrating the high gloss shimmer of the snake's ventral scales.
Most snakes have extra broad scales on the belly, each scale covering the belly from side to side. The scales of all reptiles have an epidermal component (what one sees on the surface), but many reptiles, such as crocodilians and turtles, have osteoderms underlying the epidermal scale.
A new snake species, the northern green anaconda, sits on a riverbank in the Amazon's Orinoco basin. “The size of these magnificent creatures was incredible," Fry said in a news release earlier ...
