There is much variation in the size and shape of scales among species of snakes: the [[Bushmaster|bushmaster]] for example, has scales that are large with a dermal core or osteoderm while they may be partially overlapping and keeled in the [[Rattlesnake|rattlesnake]]. The smallest scales are seen in the [[Boidae|boids]] and worm snakes.
