Actinopterygii (ray-finned fishes) > Gadiformes
(Cods) > Bregmacerotidae
Etymology: Bregmaceros: Greek, bregma = front of the head + Greek, keras, -atos = horn (Ref. 45335).
Environment / Climate / Range
Marine; brackish; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 2000 m (Ref. 26165). Subtropical; 40°N - 30°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.6 cm SL male/unsexed; (Ref. 4496); common length : 7.0 cm SL male/unsexed; (Ref. 2872)
soft rays: 58 - 69;
Vertebrae: 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.
Eastern Indian Ocean: Probably restricted to the area from West India to eastern Thailand. Reports from outside this area are most likely misidentifications (A.S. Harold, pers. comm., 18/08/98). However, larval occurrence is wide in the tropics (Ref. 9902, 46075).
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).
