Sperm Whale Illustration - Scientific Drawing of Physeter macrocephalus #1692778 (License: Personal Use)

This black-and-white engraving depicts a mature sperm whale in lateral view, showcasing its characteristic bulky head-containing the spermaceti organ-and relatively small pectoral fins. The tail fluke is slightly downturned, and fine shading conveys musculature and skin texture typical of 19th-century natural history illustrations. The image reflects historical marine biology documentation methods before modern photography.
