简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 0; 臀棘: 0; 臀鳍软条: 15 - 18. Body fairly slender, somewhat compressed. Snout very short, about 1/2 eye diameter; maxilla very short, tip bluntly rounded, reaching only a little beyond hind border of eye; gill cover canal pattern not recorded. Anal fin fairly short, its origin below about middle of dorsal fin base.
身体非常细长的, 略微扁长形的。 吻非常短又大约 1/2 眼直径; 颚骨非常短的, 顶端钝地圆的, 只有稍微达到超过眼的后部边缘; 鳃盖运河图案没有纪录。 臀鳍非常短的, 它的起源背鳍基底的大约中央下面。
Occurs in large schools together with juvenile Anchovia surinamensis and slightly larger juvenile Lycengraulis batesii, which appear to feed on the Anchoviella. Mature by about 2 cm SL; a female of 2.5 cm had 157 large eggs in the ovary. This is evidently a progenetic species (adult at juvenile stage).
形成大群的鱼群伴随着稚鱼 Anchovia surinamensis 与略大幼年的 Lycengraulis batesii, 那似乎吃 Anchoviella. 成熟时大约 2 公分 SL; 2.5 公分的一条母鱼有 157个大的卵卵巢中。 这明显地是一个 progenetic 种。 (成鱼在幼龄期)
