Environment: milieu / climate zone / distribuzione batimetrica / distribution range Ecologia

marino; acqua dolce; salmastro benthopelagico; amfidromo (Ref. 59012); distribuzione batimetrica 0 - 5 m (Ref. 86942). Tropical; 21°C - 28°C (Ref. 12468); 35°N - 6°N

Distribuzione Stati | Aree FAO | Ecosystems | Presenze | Mappa dei ritrovamenti | Introduzioni | Faunafri

Asia and Oceania: Japan southward to the Philippines, Indonesia, New Guinea and Australia. Reported from Africa: south to Coffee Bay, South Africa (Ref. 2798) and Seychelles (Ref. 4343). Widely distributed over the West tropical Pacific, from Japan to the Philippines, Indonesia, New-Guinea, North of Australia, Vanuatu and New Caledonia (Ref. 87781). The Redigobius genus is actually being revised and especially the bikolanus group that should be splitted into several taxa, leading to a revision of the group distribution also (Ref. 87781).

Biologia     Glossario (es. epibenthic)

Adults inhabit creeks, rivers and brackish estuaries (Ref. 2847, 44894). Found in tidal streams (Ref. 4343, 44894). Sometimes seen upstream a short distance from the tidal zone. Feed on small fishes and invertebrates. Not seen in markets (Ref. 12693).
