It is made up of inner layer of collagen fibres and an outer organic layer impregnated with calcium salts.

Ctenoid scales are composed of two main regions, a surface layer having a hard shell resulting from crystallized calcium salts, and a deeper layer that is built with collagen-type fibrils. Three generalized types of ctenoid scales have been categorized.
