Whale Head Anatomy: Cross-Sectional Illustration of Cetacean Cranial Structure #147710 (License: Personal Use)

This finely detailed engraving depicts a sagittal section through the head of a baleen whale, exposing the complex arrangement of the rostrum, palate, baleen plates, mandible, and associated musculature and sinuses. The illustration highlights specialized adaptations such as the elongated upper jaw, keratinous baleen racks, and airway pathways critical for filter feeding and echolocation. Labels (a-k) correspond to anatomical features identified in original zoological texts, likely from late 1800s cetacean studies.

Used in academic and museum contexts for teaching marine mammal anatomy; ideal for biology textbooks, online encyclopedias, or natural history websites where users seek authoritative visual explanations of cetacean physiology.
