This precise ink illustration depicts a sturgeon in lateral view, revealing key anatomical traits: a long, pointed rostrum, four barbels near the mouth, five rows of bony scutes along the body, and a heterocercal tail fin. The fine cross-hatching conveys texture and musculature, typical of 19th-century natural history engravings used for taxonomic reference.
