When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. [1] Dorsal scale are ...
The scales on the body of the snake are called the dorsal or costal scales. Sometimes there is a special row of large scales along the top of the back of the snake, i.e., the uppermost row, called the vertebral scales.
See Snake scales for terminology. A many-striped skink in Bali, Indonesia. Eutropis multifasciata is a species of skink that often shows prominent coloured dorsal bands. They have a number of other distinctive features that allows this species to be distinguised from other species, particularly in the detail of the arrangement of their 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 ...
This snake grows to an average of about .5 to 1 m. A fossorial species, the head is wedge-shaped and narrow with little neck delineation, which makes it easy to push through the soil. 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 ...
Enlarged vertebral scales of Banded Krait Bungarus fasciatus. Vertebral scales, in snakes, are large scales along the top of the back of the snake, i.e., the uppermost row. They are a specialised form of dorsal scales. "Vertebral" is a term associated with the backbone, but also central scales such as on the carapace of a chelonian shell. [1]
The dorsal scales, in addition to the strong primary keel, have secondary keels and tubercles, but no apical pits. The dorsal scales are arranged in 15 rows at midbody (in 17 rows on the neck). The ventrals number 203-241. The anal plate is undivided. The subcaudals number 45-61, and are divided (in two rows). [2]
In snakes, the paraventral scales are the longitudinal rows of dorsal scales that contact the ventral scales. These are the first rows of dorsal scales on either side of the body and are usually slightly larger than the scales located more dorsally. In species that have mostly keeled scales, the paraventrals are usually smooth or only weakly ...
