Piranha Fish Illustration - Scientific Drawing for Biology & Education #3069989 (License: Personal Use)

This meticulously rendered black-and-white illustration captures the anatomical precision of a piranha, emphasizing its powerful jaw, serrated teeth, large eye, and scale pattern. The fine cross-hatching technique conveys texture and depth, typical of 19th- to early-20th-century natural history engravings. Such illustrations were historically used in taxonomic guides and zoological publications to document species morphology before color photography became widespread.
