Ecology of Actinopyga echinites

Main Ref.	Conand, C., 1998
Remarks	Dwells in moderately shallow waters (despite its English common name), in sandy areas with large amounts of coral rubble; mostly on reef flats of fringing and lagoon-islet reefs; abundant in seagrass beds, on rubble flats, and compact flats where populations can reach high densities (up to 1/m) (Ref. 122); it attaches to rocks with its tube feet (Ref. 118).
