Ecology of Megastraea undosa

Main Ref.	Gotshall, D.W., 2005
Remarks	Coastal (Ref. 121668). It is found on rocks, usually in kelp beds, from low intertidal to a depth of 21 meters (Ref. 865). Also in subtidal habitats (Refs. 121666, 121667) and rocky reefs (Ref. 121668). Herbivorous (Refs. 121666, 121667), primarily feeds on the giant kelp Macrocystis pyrifera; also consumes a variety of fleshy and calcareous macroalgae (Ref. 121667).
