Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 1.7 cm SL male/unsexed; (Ref. 108789)

Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 7-9; Anal spines: 1; Anal soft rays: 7 - 9; Vertebrae: 26. This species is distinguished from its congeners by the following characters: cephalic sensory-pore system lacking only the IT pore (pattern 2); only some pectoral-fin rays are branched; pectoral-fin base have 1 or 2 prominent dark spots; dorsal/anal-fin formula usually 8/8; without occipital spots (Ref. 108789).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00286 - 0.01390), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.3 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 (10 of 100) .
