簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 2 - 7; 臀棘 0; 臀鰭軟條: 0. Distinguished in having just 6 to 9 gill rakers on the first gill arch, 8 to 11 pectoral fin rays, and just 2 caudal fin rays. Start of the dorsal fin having 1 to 3 simple elongated rays, apparently never ornamented; not forming a single or double crest but are membranously joined to each other as well as to the dorsal fin. No cristophore. Head is shallow, with gently sloping snout. (Ref. 92949). Body silvery in color. Dorsal fin rose-colored and with more than 400 soft rays (Ref. 4171). Opercular bones well-developed. Small, protrusible mouth, without visible teeth; premaxilla extending forward along dorsal profile of head; axis of maxilla oblique. Skin of fragmented body naked, studded with numerous hard tubercles. Lateral line runs along sides consisting of a chain of oblong plates to form a continuous tube (Ref. 43600).
