The frontal scale refers to one or more scales on top of the head located between the supraocular scales. In many snakes, such as colubrids and elapids, this is a single large scale or plate. In most crotalines, however, this space is occupied by numerous irregularly shaped smaller scales that may be either keeled or smooth (see interorbital scales).[1] In blind snakes (Leptotyphlops), the frontal is second plate in the median dorsal line on the crown behind the rostral scale.[2]
