Ecology of Tripneustes gratilla
 
Main Ref. Schoppe, S., 2000
Remarks Intertidal to subtidal (Ref. 106729). Inhabits shallow seagrass beds at depths of 1 to 30 m (Ref. 800). Also on rubble (Ref. 106121)and coral reef areas (Refs. 106724, 106728, 106735) like reef lagoons (Ref. 106729). Tripneustes gratilla elatensis: occurs in inland salt-ponds tolerating salinities greater than 45 ppm at 15°C (Ref. 2940). Feeds on macroalgae, seagrass, diatoms and coral tissue scraped from rocks (Ref. 2944). Omnivore (Ref. 116259). Grazing species. Dwells among rocks and boulders. Utilizes floating seaweed as cover (Ref. 129602).
