Ecology Summary - Holothuria edulis

Language:

Ecology of Holothuria edulis

Main Ref.	Conand, C., 1998
Remarks	A common shallow water species; mostly on inner and outer flats of coastal reefs, back reefs, or shallow coastal lagoons; specimens from barrier reefs have been reported to have a brown bivium and whitish trivium. Most abundant on sandy-muddy grounds with rubble or coral patches and in seagrass beds (Refs. 122, 129602). Also common on sandy-silt sand mixed with coral rubble (Ref. 92930) and those with fine and coarse sand on seagrass (Ref. 129602). Mean population density around 0.1 per square meter or not exceeding 0.1 per square meter (Ref. 122).
