Ecology of Scylla serrata

Main Ref.	Ng, P.K.L., 1998
Remarks	Prefers oceanic waters, usually found just offshore on soft muddy bottoms (Also Ref. 9773). Can be caught up to 50 m offshore as it migrates offshore to spawn (Ref. 343). Subtidal (Ref. 106854). Digs deep burrows in mangroves and soft substrates in shallow or intertidal waters (Refs. 343, 9773). Found in brackish to sea water (Ref. 77016). Forages at night. Major predator (Also Ref. 128960) of small invertebrates colonizing mangrove swamps (Ref. 8752). Feeds on shrimps, crabs, fishes, and bivalves (Refs. 99886, 102679). Benthic scavenger but prefers oysters (Ref. 9773).
