簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 臀棘 0; 臀鰭軟條: 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.
身體非常細長的, 略微扁長形的。 吻非常短又大約 1/2 眼直徑; 顎骨非常短的, 頂端鈍地圓的, 只有稍微達到超過眼的後部邊緣; 鰓蓋運河圖案沒有紀錄。 臀鰭非常短的, 它的起源背鰭基底的大約中央下面。
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).
形成大群的魚群伴隨著稚魚 Anchovia surinamensis 與略大幼年的 Lycengraulis batesii, 那似乎吃 Anchoviella. 成熟時大約 2 公分 SL; 2.5 公分的一條母魚有 157個大的卵卵巢中。 這明顯地是一個 progenetic 種。 (成魚在幼齡期)

營養階層 (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref.

Fishing Vulnerability (Ref.
