Ecology of Holothuria scabra
 
Main Ref. Conand, C., 1998
Remarks Found in shallow waters, rarely in depths of more than 10 m; mostly on inner reef flats of fringing and lagoon-islets reefs, coastal areas under terrigenous influence, and near mangroves. Burrows in mud and sandy-muddy bottoms (Also Ref. 129602) where the populations can reach high densities up to 1 per square meter (Ref. 122). Found in silty sand, often near low saline areas and frequently on Cymodocea beds, from the intertidal to a depth of 10 m. It buries in sand part of the day but is gregarious in nature (Ref. 118). Also found in intertidal seagrass beds (Refs. 106849, 129602). Benthic detritus feeder; assimilates organic matter from muddy sandy sediments, among other food sources (Ref. 101695).
