Maturity: Lm ? range ? - ? cm
Max length : 20.5 cm SL 雄魚/尚未辨別雌雄; (Ref. 189)
背棘 (總數): 0; 臀棘 0; 臀鰭軟條: 21 - 24. Snout about 2/3 eye diameter; maxilla moderate, tip somewhat bluntly rounded, reaching almost to sub-operculum, teeth becoming larger after first third of jaw. Lower gill rakers fairly short, none rudimentary. Dorsal fin origin behind midpoint of body; anal fin origin under anterior third of dorsal fin base. Silver stripe lost in larger fishes; a curve of black dots on operculum .
吻大約 2/3 眼直徑; 顎骨中等的, 頂端略微鈍地圓的, 幾乎到在三分之第一的頜之後變得比較大的子鰓蓋，齒。 下鰓耙非常短的, 沒有不發達的。 身體的背鰭起點中點後面; 在背鰭基底的前三分之一下面的臀鰭起源。 銀色的斑紋在較大的魚中失去; 在鰓蓋上的一個黑色點的彎曲。
Occurs inshore but entering brackish if not fresh water (thus probably similar to L. grossidens). Feeds on fishes (including other anchovies), perhaps also crustaceans. Nearly ripe females occurred in the Gulf of Nicoya, Costa Rica in June, August and September, and juveniles of 3.3-4.5 cm in January and October. TL = 1.257 SL.
生活於近海但是進入半鹹淡水如果不是淡水.(如此可能類似 L. grossidens) 吃魚 (包括其他的鯷魚), 也許也捕食甲殼類動物。 幾乎成熟的雌性在六月,八月與九月出現在哥斯大黎加的尼哥亞灣了, 與在一月與十月的 3.3-4.5 公分的稚魚。 TL=1.257 SL。
