Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); A resident intertidal species with homing behavior (Ref. 32612, 48637) and amphibious air-breather (Ref. 31184, 79840), found in brackish mud flats in mangrove and nipa palm areas. Found in both littoral and estuarine; able to climb out of water, in mangrove swamps and burrowing into intertidal mud banks (Ref. 4756). Occasionally in the lower parts of freshwater streams (Ref. 2847, 44894, 48637, 79840). Actively shuttling back and forth between rock pools and air (Ref. 31184). It feeds on worms, crustaceans, and insects (Ref. 37816). Can stay out of the water for up to 37 h if kept moist (Ref. 51276).
