Squid Anatomy Illustration - Classic Scientific Drawing #42513 (License: Personal Use)

This monochrome illustration depicts a squid in lateral view, rendered in fine-line stipple and cross-hatching typical of 19th-century natural history publications. The mantle is densely speckled, the eight arms and two longer tentacles are clearly differentiated, and the fins extend laterally along the posterior end. The image evokes classic marine biology textbooks and serves as both educational and decorative material.
