Cephalopod Anatomy Diagram - Squid Structure and Labeled Parts #276142 (License: Personal Use)

This vintage scientific illustration presents two views of a cephalopod-likely a squid-with precise linework and lettered annotations identifying key anatomical features such as the mantle (C), fins (F), arms (I), tentacles (L), and internal organs like the ink sac (Or) and digestive gland (G). The top diagram shows the dorsal aspect with musculature and segmentation, while the bottom reveals the lateral view including the head, beak (h), radula (k), and gill structure (e). Such diagrams were foundational in comparative zoology and remain valuable for teaching molluscan morphology.

Used in educational contexts-biology textbooks, museum exhibits, or online learning platforms-to teach invertebrate anatomy. Matches user intent for academic study, historical science illustration appreciation, or biological reference.
