Cuttlefish Anatomy and Behavior | Marine Biology Guide #74777 (License: Personal Use)

This illustration depicts a cuttlefish (Sepia officinalis) in mid-swim, highlighting its ornate tiger-striped mantle, large W-shaped pupil, and two long, slender tentacles used for capturing prey. The animal’s fin undulates along its body for precise maneuvering, while chromatophores enable rapid color shifts for communication and camouflage. Its internal cuttlebone provides buoyancy control, essential for its demersal lifestyle.
