Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 7.9 cm SL (female)

Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 15; Anal spines: 4; Anal soft rays: 10; Vertebrae: 27. The slender, slightly compressed body is probably mainly, if not entirely, red in life; 5 rows of oblique scales on cheek; body slender, the depth 3.1 in SL; head length (HL) 2.55 in SL; very large eye, 2.6 in HL; very narrow suborbital shelf; anterior end of the nasal bone is rounded; moderately large nasal fossa spineless; surface or medial edge of the nasal bone spineless; third dorsal spine longest, 2.2 in HL; spinous and soft portions of dorsal fin completely separated; third anal spine 1.35 in HL; pointed caudal fin lobes (Ref. 27370).

Biology     Glossary (e.g. epibenthic)

The species may penetrate deeper water (suggested by the large eyes); the 49 m depth could be near the upper limit of its depth range (Ref. 27370).

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=0.01660 (0.00806 - 0.03417), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.6 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) .
