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.
These scales were easily dispersed after death; their small size and resilience makes them the most common vertebrate fossil of their time. [ 14 ] [ 15 ] The fish lived in both freshwater and marine environments, first appearing during the Ordovician , and perishing during the Frasnian–Famennian extinction event of the Late Devonian .
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.

The Rainbow Fish responds and refuses in a rude manner. The small blue fish tells the ...
The overall colour is bright red fading to pink on the lower flanks and then to whitish on the abdomen. There is a series of short wavy oblique blue lines on the sides flanks above the lateral line which are created by spots on the scales, there may be yellow streaks below the lateral line. The anal fin is pinkish red; the caudal fin is red ...
The Jewish laws of kashrut, which only permit the consumption of fish with both scales and fins, forbids sturgeon, as they have ganoid scales instead of the permitted ctenoid and cycloid scales. While all Orthodox groups forbid the consumption of sturgeon, some Conservative groups do allow it. [ 68 ]
Scales are relatively large and easily lost when the fish is handled. The mouth is small and upturned. Two characteristics can distinguish the golden shiner from all other minnows: (1) the lateral line has a pronounced downward curve, with its lowest point just above the pelvic fins; and (2) there is a fleshy keel lacking scales on the belly ...
