بوم شناسي
; دريايي; لب شور; اقیانوس رو (Ref. 51243); تغييرات عمق 0 - 2000 m (Ref. 26165). Subtropical, preferred 28°C (Ref. 107945); 25°N - 6°N, 62°E - 100°E
Indian Ocean: confirmed from the Arabian Sea and Bay of Bengal. Reports from outside this area are most likely misidentifications (A.S. Harold, pers. comm., 18/08/98) and name reported from western Pacific may be a misidentification of B. pseudolanceolatus (Ref. 114229).

Max length : 9.6 cm SL جنس نر / بدون خواص جنسي; (Ref. 4496); common length : 7.0 cm SL جنس نر / بدون خواص جنسي; (Ref. 2872)
خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 57-66; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 58 - 69; مهره ها: 52 - 58. Body is elongate, brownish and with speckling above and silvery below. The cheek and lower head also silver. Single occipital ray long and delicate, extending to near the middle of the second dorsal fin (Ref. 46075). Pelvic fins are jugular.
If taxonomy is correct, both onshore in brackish water and oceanic. According to larval survey, occurrence in the tropics is wide (Ref. 9902, 45075). Feed on planktonic crustaceans. Also caught with bagnets (Ref. 2872).
