简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 2 - 7; 臀棘: 0; 臀鳍软条: 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).
身体银色的颜色。 背鳍玫瑰-色彩而且与超过 400个软鳍条.(参考文献 4171) 鳃盖硬骨发展良好的。 小又能伸展的嘴, 没有看得见的齿; 向前延伸的前颌骨沿着头部的背面轮廓; 颚骨斜角的轴。 碎片的身体的皮肤裸露的, 布满颗粒有很多的坚硬小瘤。 侧线沿着被包含长方形碟的链形成一个连续的管的侧边。 (参考文献 43600)
Rare species, known from only seven specimens. Occurs in the open ocean habitat (Ref. 4171). Found only in the southern oceans from 25°S to 59°S. Apparently also capable of autotomy, unique amongst lampridiforms. Early life history stages (eggs and larvae) unknown. Predators, prey, and parasites unknown (Ref. 92949).
