Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 51 - 68. Diagnosis: adipose fin present; inner side of pectoral spine feebly serrated; 51-68 anal fin rays; vomerine teeth usually absent; a dark triangular blotch at base of caudal fin (Ref. 81643). Coloration: in life: pale, more or less transparent, with small triangular spot at base of caudal fin (Ref. 81643). Preserved specimens: head and back covered with small brown-black spots; fine mid-lateral line terminates in small spot at base of caudal fin; band of chromatophores sometimes present along anal fin base; pelvics colourless, pectoral fin often mottled, anal also sometimes mottled (Ref. 81643).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00270 - 0.01286), b=3.03 (2.84 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
Price category (Ref. 80766):   Unknown.
