Ecology of Protoreaster nodosus
 
Main Ref. Schoppe, S., 2000
Remarks Occurs on seagrass beds and seaweed areas (Refs. 82802, 89727), particularly on reef flats (Ref. 85384). It is known to be an extra-oral feeder (Ref. 85384) or microphagous feeder (Ref. 98606). Feeds on microbial and microalgal films, both living and decomposing seagrass blades, and filamentous green algae (Ref. 98606).
