Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 76833)

Short description Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 10-11; Anal spines: 3; Anal soft rays: 5 - 6. Distinguished from all other Scorpaenodes species by having the first two spines on the suborbital ridge extending dorsally above the lower orbit margin; no distinct dark spot on opercle, subopercle, or spinous dorsal fin; pectoral fin rays usually 17; vertical scale rows 39-43; head and upper body light cream overlaid by dark brown to black pigment pattern; lower half of body light cream to white, edges of scales on lower half pink (Ref. 46823); Suborbital ridge with four spinules; presence of interorbital and coronal spines, small; depth of body 2.8-3.1 in SL (Ref. 90102).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 26.1 - 29.4, mean 28.5 (based on 1225 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00595 - 0.02544), b=3.02 (2.85 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
