marina; brackvatten; djupintervall 0 - 50 m (Ref. 82332). Tropical; 31°N - 25°S, 30°E - 172°W (Ref. 189)
Indo-Pacific: widespread in Indian Ocean, including Red Sea, coasts of East Africa to Madagascar and Mauritius, Sri Lanka and Andaman Islands, but no Indian specimens known (Ref. 189); and in western central Pacific, including Indonesia, the Philippines, Papua New Guinea, northern and eastern coasts of Australia, and eastward to Tonga (Ref. 189). No records are known from South China Sea or to the north, but the Ogasawara, Bonin Islands, record seems reliable (Ref. 189). Its occurrence in Thailand (Ref. 1632) needs confirmation.

Maturity: Lm ? range ? - ? cm
Max length : 16.0 cm SL hane/ej könsbestämd; (Ref. 54980); common length : 10.0 cm TL hane/ej könsbestämd; (Ref. 5450)
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 14 - 16; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 29 - 34. Diagnosis: Body not strongly compressed, belly rounded before pelvic fins, with 4-9 pre-pelvic and 7-10 post-pelvic scutes, the pre-pelvic scutes ending below the pectoral fin base or behind it; in total 12-18 keeled scutes; maxilla short, reaching to just beyond front border of pre-operculum, tip pointed; gillrakers 18 to 26 (Ref. 189). It closely resembles Thryssa encrasicholoides, which has 1 or 2 small but armless keeled scutes immediately behind the isthmus, also maxilla tip blunter; other species of Thryssa have a complete series of pre-pelvic scutes from isthmus to pelvic fin base; Stolephorus species lack post-pelvic scutes; and Lycothrissa has canine teeth (Ref. 189).
Marine, pelagic and presumably schooling (Ref. 189, 1602, 5213), at depths of 0-50m (Ref. 82332). Found mostly inshore in bays, lagoons, harbours, mangrove pools and estuaries, thus apparently able to tolerate lowered salinities (Ref. 189, 30573). It contributes to general clupeoid catches, but no special fishery (Ref. 189). Used as a baitfish in Pacific Ocean (Ref. 189).
