Planarian Anatomy Diagram - Key Structures and Functions #1760978 (License: Personal Use)

This scientific illustration depicts a dorsal view of a planarian (a free-living flatworm), emphasizing its bilateral symmetry, cephalic ganglia, pigment-cup eyespots, muscular pharynx, and highly branched gastrovascular cavity that distributes nutrients without a circulatory system. Blue arrows point to major structures including the auricles, brain lobes, and intestinal branches, supporting classroom or textbook learning. The orange and yellow color coding distinguishes tissue layers and functional systems.

Used in biology textbooks, online educational platforms, and university lecture slides to teach invertebrate anatomy, regeneration, and simple organ systems; targets students and educators seeking clear visual aids for flatworm physiology.
