D. Marcus Elieser Bloch's, ausübenden Arztes zu Berlin, Oeconomische Naturgeschichte der Fische Deutschlands, Berlin, Auf Kosten des Verfassers und in Commission bei dem Buchhändler Hr. Hesse, 1782-1795., This illustration showcases a detailed depiction of a fish, characterized by its elongated body and prominent dorsal fin. The fish features distinct black and yellow stripes running along its sides, contributing to its striking appearance. Its fins are well-defined, with the pectoral fins showing a gentle curve. The head is portrayed with a rounded snout and a slightly open mouth, hinting at its predatory nature. Above the fish, a small oval shape suggests a space for annotation, typical of scientific illustrations intended for study. The overall composition emphasizes the intricate details of the fish's anatomy, making it a valuable reference for ichthyology.
