Etymology: Bregmaceros: Greek, bregma = front of the head + Greek, keras, -atos = horn (Ref. 45335).
Eponymy: John McClelland (1805–1875) was a British doctor with interests in geology and natural history. [...] (Ref. 128868), visit book page.

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)

背棘 (总数) : 0; 背的软条 (总数) : 57 - 66; 臀棘: 0; 臀鳍软条: 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.
身体是细长的, 褐色的与具有小的斑点在上面与下面银色的。 颊部与头部下半部也银色的。 单一后头骨的鳍条长而娇弱的, 延伸到第二个背鳍的中央附近.(参考文献 46075) 腹鳍是咽喉的。

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).
如果分类学是正确的,既岸边半淡咸水的且大洋性的。 根据幼虫的调查, 广泛发现于热带.(参考文献 9902,45075) 捕食浮游性甲壳动物。 也用袋网捕获。 (参考文献 2872)
