Language:

Main Ref.	Rainboth, W.J., 1996
Remarks	A common species that inhabits mangroves and silty (Also Ref. 9773), rocky areas; occasionally found in rubble reef areas. Only single individuals were observed; many individuals found scattered over a small area (Ref. 420). Found primarily in lower estuaries, usually in mangroves. This is the species of the genus that is found farthest inland. Feeds on small invertebrates (Ref. 12693). Feeds on mud prawns and mollusks. Aggresively territorial (Ref. 9773).
