Ref. principal Ng, P.K.L., 1998
Notas Immediate subtidal to a depth of 40 m (Ref. 801), on sandy to sandy-muddy substrates in areas near reefs, mangroves, and sea grass and algal beds (Ref. 343). Juveniles tend to occur in shallow intertidal areas (Ref. 343). Burrows in sand when disturbed; carnivorous and voracious predator (Ref. 801). Host to protozoans, helminths and crustaceans (Ref. 104981).
