簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 0; 背的軟條 (總數) : 14 - 15; 臀棘: 0; 臀鰭軟條: 19 - 22; 脊椎骨: 42. Diagnosis: Body slender, its depth 22-25% of standard length; pre-pelvic scutes not strongly keeled, beginning under or behind base of last pectoral finray, 8-10 pre-pelvic and 6-9 post-pelvic scutes, belly rounded; snout bluntly rounded; lower jaw not projecting, exactly meeting tip of upper jaw when mouth closed, deepest at mid-point of jaw, with small saw-like teeth on each side; pre-maxillae with small teeth pointing downward; maxilla very slender, its blade over 3 times as long as deep, upper edge ridged, lower edge without denticulations; posterior supra-maxilla minute, virtually without anterior shaft; lower gillrakers 14-17; silver stripe along flank, narrower anteriorly (Ref. 188, 28136). The presence of small horny denticles on snout and edges of mouth on the skin of the maxillary is typical for this species (Ref. 188, 93833). It closely resembles Potamothrissa obtusirostris, which lacks dermal denticles on the snout and has more post-pelvic scutes, 9-12 vs. 6-9; Potamothrissa acutirostris has a pointed snout and more gillrakers, 16-18 vs. 14-17 (Ref. 188, 28136). Other pellonulines lack saw-like teeth at the sides of the lower jaw (Ref. 188).
前腹鰭鱗甲不有明顯的龍骨, 開始在或下面最後胸鰭鰭條的在後基底,8 到 10+7 到 9. 吻圓的; 下頜不是突出, 當嘴巴閉合時完全碰到上頜的頂端, 深的在中央點, 有小的像見到一樣的牙齒在兩邊; 前顎有小的分向朝下的齒; 顎骨非常細長的; 第二個上顎骨細小又事實上沒有軸。

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00433 - 0.01920), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
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 vulnerability (10 of 100).
