A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages.
The specific name macrolepidotus means "large scale" in Latin, which is considered an accurate reflection of its scale size; [7] the scales themselves are cycloid. [6] The original description gave it the common name "large-scaled chalceus". [8] The genus name Chalceus comes from the Greek word chalkos, which means brass or copper. [2]
They have a rounded head and a terminal mouth, although the snout hangs a little bit over the mouth. The dark coloring on the edges of the scales cause a cross-hatched look along the body. The scales on these fish are cycloid scales, a type of leptoid scale. It is possible to find the age of a fish from the rings on the scales.
Quillback are typically 15–20 inches on average, weighing between 1 and 4 pounds. However, they can grow up to 26 inches and weigh 10 pounds. The quillback has a nearly straight, hyper-sensitive lateral line, composed of at least 37 lateral line scales. This helps the fish locate predators and prey. [citation needed]
Reptile scale types include: cycloid, granular (which appear bumpy), and keeled (which have a center ridge). Scales usually vary in size, the stouter, larger scales cover parts that are often exposed to physical stress (usually the feet, tail and head), while scales are small around the joints for flexibility.
Cycloid scales are small, oval-shaped scales with growth rings like the rings of a tree. They lack enamel, dentin, and a vascular bone layer. Bowfin and remora have cycloid scales. Ctenoid scales are similar to cycloid scales, also having growth rings, lack enamel, dentin, and a vascular bone layer. They are distinguished by spines or ...

Clupeidae is a family of clupeiform ray-finned fishes, comprising, for instance, the herrings and sprats.Many members of the family have a body protected with shiny cycloid (very smooth and uniform) scales, a single dorsal fin, and a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals.
