简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 1; 背的软条 (总数) : 13 - 17; 臀棘: 0; 臀鳍软条: 3 - 5. Esca with compressed posterior and anterior crests; anterior margin of vomer nearly straight; minute skin spines present over most of body (Ref. 13608). Branchiostegal rays 6 (Ref. 36493). Caudal-fin rays 8. Scales are cone-shaped, hollow and translucent; with circular base and a free edge pointing towards the caudal region. Left otolith, oblong shape with regular edges, inner face does not present rostrum, antirostrum or cisure (Ref. 41244).
Distinguishing characteristics of metamorphosed female: least outside width between frontals 13.5-28.6% SL; upper jaw with 48-134 teeth, lower jaw 32-78 teeth; length of longest tooth in lower jaw 8.4-25% SL; width of pectoral fin lobe 10.7-17.8% SL; width of escal bulb 4.3-8.6% SL; length of illicium 32.4-60.8% SL; skin with minute spinules over most of body; relatively thick integument 1.55 mm (Ref. 86949). Distinguishing characteristics of metamorphosed male: upper denticular with 9-13 ventrally directed anterior teeth and posteromedial series of 8-11 teeth; lower denticular 12-24 teeth; posterior nostril contiguous with eye; at most 24 olfactory lamellae; skin naked or spinulose (Ref. 86949).
饵球有扁长形的在后部与前面的冠; 犁骨的前缘几乎是直的; 细小的皮肤棘存在的在大部分的身体之上.(参考文献 13608) 鳃条骨 6.(参考文献 36493) 尾鳍鳍条 8. 鳞片是圆锥体-形状的，空的与半透明的; 有圆形的朝向尾鳍区域的基底与一个分离的边缘。 左边的耳石, 长方形形状具有规则的边缘, 内面不会呈现喙， antirostrum 或 cisure.(参考文献 41244)
Meso- and bathypelagic (Ref. 58302). Males dwarfed and non-parasitic (Ref. 4491). Caught with plankton nets (Ref. 559). Capable of catching and swallowing prey larger than itself, as witness the approximately 24.0 cm SL specimen of Chauliodus sp. in the stomach of a 6.6 cm SL individual (NMNZ P 14537) (Ref. 58502). Larvae are found primarily in upper 100 m (Ref. 36493). Oviparous, with planktonic larvae (Ref. 36493). Eggs are presumably contained in floating gelatinous rafts (Ref. 36493).
雄性矮种的了与非寄生.(参考文献 4491) 用浮游生物网捕获了。 (参考文献 559) 仔鱼主要地在上面的 100 公尺中被发现。 (参考文献 36493) 卵生的, 仔鱼为浮游性.(参考文献 36493) 卵是可能包覆在漂浮的凝胶状的筏中.(参考文献 36493)
