Fish

Generic bony fish shown in side view in a simple scientific or textbook illustration style, with a streamlined laterally compressed oval-to-elongated body, slightly pointed or tapered head, visible round eye, small slightly open mouth, and distinct gill cover behind the eye. The body is covered in overlapping smooth scales in silvery, silver-blue, blue-gray, or blue-green tones, often with a paler underside and slightly darker dorsal side. Fins include a single dorsal fin on top, paired pectoral fins at the sides, paired pelvic fins underneath, an anal fin near the rear underside, and a forked tail fin. Overall appearance is a naturalistic generalized freshwater or marine bony fish with a hydrodynamic profile.
