背棘 (總數): 9; 背的軟條 (總數): 10; 臀棘 3; 臀鰭軟條: 7 - 8. Diagnosis: body fusiform and compressed; snout pointed; mouth strongly protrusible; nostrils contiguous, positioned nearer to eye than to snout tip; dorsal fin deeply notched; tips of pectoral fins not reaching to anal-fin origin; scales cycloid on head and finely ctenoid on body; scales of interocular space reaching anterior border of eyes; tip of spinous dorsal fin with a black spot, underlined by a whitish band (Ref. 57394). Coloration: back olivaceous, sides silvery; a characteristic black spot at tip of spiny part of dorsal fin; young individuals may show dark vertical bars on back and sides (Ref. 57394).

生物學特性     字彙 (例如 epibenthic)

A coastal species entering estuaries, lower courses of coastal rivers, and lagoons (Ref. 4323, 7352, 57394). Found over sand or mud bottoms (Ref. 3722, 57394). Feeds on fish, shrimps, mollusks, zooplankton and detritus (Ref. 28587); including other benthic crustaceans and polychaetes. Forages at daytime in small groups, hovering close to the bottom and either picks off prey on the substrate or digs into it sifting the mouthed sediment through its opercular openings. Its conspicuous black tip on dorsal fin is mimicked by juvenile guianan snooks, Centropomus mexicanus, an example of aggressive mimicry (Ref. 43465). Marketed fresh but not highly esteemed (Ref. 3722).

一個沿岸魚種進入河口,沿海的河川與潟湖.(參考文獻 7352,4323) 發現在沙或泥底部上了。 (參考文獻 3722) 吃魚,蝦,軟體動物,浮游動物與碎屑;(參考文獻 28587) 包括其他的底棲甲殼動物與多毛類動物。 在白天覓食形成小群魚群, 盤旋接近底部與或剔啄外海的捕食底部或者深入經過它的鰓蓋開口篩撒嘴巴沉澱物的它。 在背鰭上的它的顯著黑色的頂端被幼年的 guianan 土魠魚, 墨西哥鋸蓋魚〔Centropomus mexicanus〕 ,一個侵略性擬態的例子擬態。 (參考文獻 43465) 在市場上銷售生鮮地了但是不是深受喜愛.(參考文獻 3722)
