The rostral scale, or rostral, in snakes and other scaled reptiles, refers to the median plate (scale) on the tip of the snout that borders the mouth opening.[1] It corresponds to the mental scale in the lower jaw. The term pertains to the rostrum, or nose. In snakes, the shape and size of this scale is one of many characteristics used to differentiate species from one another.
