簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 臀棘: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; eye not more than 20% of head length, and 26% of head width; in adults, post-orbital length at least 60% of snout length; maxillary barbels usually longer than head (except in young individuals), unbranched, without tubercles but with a broad, black basal membrane; outer mandibular barbels with rather long, tuberculate ramifications; branches of inner mandibular barbels shorter and strongly globose; mandibular teeth long, numbering 27-38 (33 in the holotype); dorsal-fin spine smooth anteriorly; denticulations of pectoral-fin spines finer on outer than on inner margin; humeral process not keeled ventrally, triangular, slender and pointed in young specimens, and deep, more strongly arched, and more blunt posteriorly in adults; dorsal- and pectoral-fin spines prolonged into a black filament; adipose fin not very well developed; head more flattened in young than in adults; outer margins of caudal-fin lobes black-edged; body covered with fine specks (Ref. 57223).
Coloration: body rather pale and covered with fine black specks and with larger spots in young individuals; rayed fins light and often spotless, but adipose fin always spotted; outer margins of caudal-fin lobes black-edged; broad black spot above humeral process (Ref. 57223).
Maximum TL was recorded at 28.1 cm (Ref. 7362, 57223). Oviparous (Ref. 205).
最大體長TL記錄為 28.1 公分。 (參考文獻 7362) 卵生的.(參考文獻 205)

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=0.01047 (0.00635 - 0.01728), b=2.81 (2.68 - 2.94), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
