Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 48798)

Short description Morphology | Morphometrics

Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 19-21; Anal spines: 0; Anal soft rays: 14 - 15. Spinous dorsal short with anterior spines longest; caudal slightly rounded; pectorals rounded, lower 8 rays exserted, middle rays lengthened reaching anal insertion; pelvic fins reaching anus (Ref. 6885). Color pale brown, lighter ventrally; dark band through eye; eye and cirrus black; dorsal fins speckled, with spinous fin darker; usually 4 dark saddles across back, and dark band at base of caudal fin; posterior edge of caudal darker (Ref. 6885). Recognizable by having a combination of gill membranes fused to isthmus, strong longitudinal depression in occiput, scales embedded in papillae covering body except in axilla, moderate-sized spinous dorsal, second dorsal with fewer than 22 rays, and a black band through eye (Ref. 6885).

Biology     Glossary (e.g. epibenthic)

Occurs near shore and to 73 m depth, on sand and rock bottoms and shallow exposed areas (Ref. 2850).

Estimates based on models

Preferred temperature (Ref. 123201): 3.5 - 11.1, mean 7.5 °C (based on 214 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6289   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00441 - 0.02728), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
