Starfish Digestive System Anatomy Diagram - Marine Biology Education #1896632 (License: Personal Use)

This educational illustration depicts a starfish with its cardiac stomach everted through the mouth to digest prey externally, while the pyloric stomach and digestive glands process nutrients internally; a fern frond is shown as an example of ingested organic matter. The blue tube feet illustrate locomotion and feeding functions, connected to the water vascular system.

Used in marine biology textbooks, online learning modules, and museum exhibits to explain echinoderm feeding mechanisms; targets students, teachers, and science enthusiasts seeking visual understanding of starfish physiology.
