Nota: The seasons are arbitrarily classified into the southwest monsoon (June-September), postmonsoon (October-January) and premonsoon (February-May).
Loc:
Atlant. (off N Ste Helene), E Medit (Israel coast), Suez Canal (Suez Bay, Port Taufik, Bitter Lakes: very common, Ismaïlia, Lake Timsah, El Guiar, El Kantara, El Tineh, Ras-el-Ech, not Port Said after Gurney, 1927), , Safâga, Red Sea, Oman Sea, Bombay, Mandovi-Zuari estuary, Kerala, Goa, Sri Lanka, India (NW, Saurashtra coast, Godavari estuary, Kinada Bay, Chilka Lake, Poiintcalimere, Manamelkudi, ), Burma, Indonesia (SW Celebes).
N: 26 (Atlant.: ?1; Medit.: 1; Suez Canal: 4; Red Sea: 4; N Indian: 16, Indonesia: 1)

Rem.: ± saumâtre, estuaire-néritique.
Les tailles semblent corrélées avec la salinité.
Cette forme signalée off Irlande SW par I.C. Thompson (1903 a, p.31) nécessite d’être confirmée, ainsi que la forme signalée par Dakin & Colefax (1933, p.207) en Australie (Nouvelle-Galles du Sud).
Peut-être introduit en Méditerranée à partir de la Mer Rouge.
