The frontal 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 crotalids, however, this space is occupied by numerous irregularly shaped smaller scales that may be either keeled or smooth (see intersupraoculars).[1]
