In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales.[1]

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 easiest to count diagonally, starting with the paraventral scale row.[1] In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.[2]
