Bregmacerotidae (Codlets)
Etymology: Bregmaceros: Greek, bregma = front of the head + Greek, keras, -atos = horn (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態学
; 海; 汽水性の; 海洋回遊性 (Ref. 51243); 深さの範囲 0 - 2000 m (Ref. 26165). Subtropical; 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).
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 9.6 cm SL オス/雌雄の選別がない; (Ref. 4496); common length : 7.0 cm SL オス/雌雄の選別がない; (Ref. 2872)
背面の脊椎 (合計): 0; 背鰭 (合計): 57-66; 肛門の骨 0; 臀鰭: 58 - 69; 脊つい: 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).
