Earthworm Anatomy Diagram - Clitellum and Segmentation Explained #3816113 (License: Personal Use)

This scientific illustration depicts a common earthworm (Lumbricus terrestris) in lateral view, emphasizing key anatomical features including the clitellum-a saddle-like structure involved in reproduction-and the annular segmentation that defines its body. The alternating brown and white bands represent muscle layers and cuticle patterns, while the tapered anterior end suggests sensory structures like the prostomium. The style is clean and educational, suitable for textbooks or digital learning modules.

Used in biology curricula, ecology websites, and agricultural extension materials to teach invertebrate anatomy, soil health, and composting. Matches user intent for visual learning, homework help, or科普 content about decomposers.
