Ecology of Periophthalmus barbarus
 
Main Ref. Harrison, I.J. and P.J. Miller, 1992
Remarks Amphibious air-breather (Ref. 31184) that skips or walks on sand or mud in search of food; that is, on exposed intertidal mud flats of estuarine mangrove swamps. Aided with a 'hydrodynamic tongue' in which it holds water in its mouth to grab and manipulate prey on land. Found to be more effective predators on land than in water (Ref. 100787). Feeds chiefly on arthropods (crabs, insects, etc.) of the mud surface. Also included in the diet is the white mangrove, Avicennia nitida (Ref. 3026).
