Eponymy: Professor Dr Boyd Wallace Walker (1917–2001) was an American fisheries biologist; ultimately Professor Emeritus of Zoology-Fisheries at the University of California, Los Angeles, where he worked for over three decades (1949–1980). [...] (Ref. 128868), visit book page.

Maturity: Lm ? range ? - ? cm
Max length : 14.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 96339)
背棘 (总数) : 0; 臀棘: 0; 臀鳍软条: 23 - 32. Snout moderately pointed, about 3/4 eye diameter; maxilla long, tip sharply pointed, reaching to or just beyond gill opening, but shorter and more blunt at 4 to 5 cm standard length; gill cover canals of walkeri-type. Pectoral fins large, tip reaching to beyond pelvic fin base; anal fin origin below dorsal fin origin or a little behind. Silver stripe along flank, as eye in some places.
吻一般尖, 大约 3/4 眼直径; 颚骨长的, 顶端非常尖的, 延伸到或正好超过鳃裂, 但是更短与更更钝在 4 到 5 公分标准长度; walkeri 的鳃盖运河-类型。 胸鳍大的, 顶端延伸到超过腹鳍基底; 在背鳍起点之下的臀鳍起源或稍微往后。 银色的斑纹沿着侧面, 如眼在一些地方中。
Presumably schooling and most often found in warm, murky waters near shore and in bays near river mouths (specimens taken some km up the Rio Santiago, Nayarit, Mexico). Capable of tolerating lower salinities than that of the sea (Ref. 9298). The ovarian eggs are elliptical. Caught as a by-catch of encircling, lamparo, and trawl nets (Ref. 9298).
推测为群游而且最时常发现于温暖的, 浑浊的水近岸与在河口 (占据一些公里上游 Rio 圣地亚哥， Nayarit ，墨西哥的标本) 附近的海湾中. 能够超过海洋的容忍低的盐度。 (参考文献 9298) 卵巢的卵是椭圆的。 捕捉作为一个围网，灯光诱捕与拖网的误捕.(参考文献 9298)
