Found in low tidal to 130 m in crevices and stones; dead specimens to 274 m (Ref. 337); also intertidal on rocks and coral (Ref. 75831). Commonly attached via strong byssal threads to the undersides of rock slabs and boulders in the lower eulittoral subzone and to dead coral and rocks in the shallow subtidal (Ref. 102838). Also found on fine gray sand (Ref. 77792). Reported from Hong Kong to be found on the ceilings and walls of submarine caves (Ref. 126058).
