Ecology of Stichopus horrens

Main Ref.	Conand, C., 1998
Remarks	A reef species mostly found in shallow areas in coastal reef and lagoons from near the surface to a depth of 25 m; generally occurs in seagrass beds, rubbles or hidden in reef flats or dead corals (Ref. 800), and muddy-sand bottoms (Ref. 122); on algal beds and on clean sandy bottoms. A pea crab is known to live in the cloacal chamber (Ref. 118). A nocturnal species. Populations not reaching high densities, with mean of around 0.007 per square meter. Biology poorly known (Ref. 122).
