Bregmacerotidae (Codlets)

Etymology: Bregmaceros: Greek, bregma = front of the head + Greek, keras, -atos = horn (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態學
海洋; 半鹹淡水; 海洋洄游的 (Ref. 51243); 深度上下限 0 - 2000 m (Ref. 26165). 亞熱帶的; 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).
東印度洋: 可能侷限於區域從印度西部到泰國東部了。 報告從在這區域以外非常可能是誤鑑 (A.S. 哈洛德， pers. comm。,18/08/98). 然而，仔魚的分佈是廣泛的在中熱帶。 (參考文獻 9902,46075)

Maturity: Lm ? range ? - ? cm
Max length : 9.6 cm SL 雄魚/尚未辨別雌雄; (Ref. 4496); common length : 7.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 2872); 最大體重: 8.50 g (Ref. 128684)
背棘 (總數): 0; 背的軟條 (總數): 57-66; 臀棘 0; 臀鰭軟條: 58 - 69; 脊椎骨: 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.
身體是細長的, 褐色的與具有小的斑點在上面與下面銀色的。 頰部與頭部下半部也銀色的。 單一後頭骨的鰭條長而嬌弱的, 延伸到第二個背鰭的中央附近.(參考文獻 46075) 腹鰭是咽喉的。
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).
如果分類學是正確的,既岸邊半淡鹹水的且大洋性的。 根據幼蟲的調查, 廣泛發現於熱帶.(參考文獻 9902,45075) 捕食浮游性甲殼動物。 也用袋網捕獲。 (參考文獻 2872)
