簡短描述
檢索表 | 型態特徵 | 形態測量圖
Head about as wide as deep, depressed anteriorly; middle of length of head behind anterior border of pupil. Snout short and broadly protruding, with acute rostral spine; lateral margin strongly curved. Teeth in premaxillaries conical, not arrow-shaped, in 5 to 8 irregularly oblique series, forming a wide band as a whole, those of outer series evenly enlarged and widely spaced. Scales on body large, hexagonal, and rather deciduous; spinules stout and pungent, forming 4-11 divergent ridges, last spinule of each series more or less projecting beyond apical margin of scales. Scales on head coarser, less imbricated, and more adhesive than those on body; scales 7 or 8 in a longitudinal series on nasal crest, with spinous rows radiating in all directions from center of each scale, spinules never on ridges but independently rising from surface of scales. This median series of scales followed on each side by a single series of less-modified scales. Nasal fossa naked. No naked area on dorsal surface of snout, but a naked groove extending from base of rostral spine backward to interorbital space alongside median rostral series of scales. Underside of head, including mandibular regions and branchiostegal membranes, entirely naked. Vent immediately before anal fin and preceded by a luminous organ of short type (Ref. 54421).
頭部深地大約等寬於,前面地扁平的; 瞳孔的頭長在後前緣的中央。 吻短而且寬廣地凸出, 藉由尖銳的嘴棘; 側面的邊緣強烈的彎曲。 在前上頜骨的齒錐形, 不箭-形狀的, 在 5 到 8 中不規則斜的系列, 形成一個寬的條紋作為一個全部，均勻地被增大而且分開很遠的外部系列的。 在身體上的鱗片大的﹐六角形的﹐與相當易脫落; 小刺矮胖而尖銳的, 形成 4 - 11 發散的脊, 持續每系列的小刺約略突出的超過鱗片的頂上邊緣。 在頭部上的鱗片比較粗的﹐比較不層疊, 與更多的黏性物超過在身體上的那些; 鱗片 7 或 8 在鼻的冠上形成一縱列, 在脊上從不有刺狀的往四面八方從每個鱗片的中心放射的列，小刺但是獨立地從鱗片的表面升起。 這中央的成列鱗片在一個單一系列比較少量的兩邊上跟隨了-修正鱗片。 鼻窩裸露的。 沒有裸露區在背面上吻, 但是一個裸露的凹槽對眼間隔並排靠攏著中央的嘴成列的鱗片向後地從嘴棘的基底延伸。 頭部的下面, 包括顎的區域與鰓蓋薄膜, 完全裸露。 在臀鰭正前方的排洩孔而且前面有一個短類型的發光器官.(參考文獻 54421)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00194 - 0.01707), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

營養階層 (Ref.

回復力 (Ref.

Fishing Vulnerability (Ref.
