Anal scale

In snakes, the anal scale or anal plate is the scale just in front of and covering the cloacal opening. This scale can be either single ("anal entire") or paired ("anal divided"). When paired, the division is oblique.^[1]^[2] The anal scale is preceded by the ventral scales and followed by the subcaudal scales.
