Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 14 - 15; Anal spines: 2; Anal soft rays: 15 - 17; Vertebrae: 34. Olivaceous with 7 short dark brown double bars on side of body and rows of small pale blue spots (Ref. 13442).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Adults occur in intertidal areas (Ref. 31184), like tide pools, rocky slopes, and places where there are boulders on the bottom (Ref. 5521). Actively shuttle back and forth between rock-pools and air (Ref. 31184). They breathe air (Ref. 31184) and can remain out of water for up to 2 hours if kept moist (Ref. 51276). Feed mainly on algae (Ref. 13442). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 26.5 - 28.2, mean 27.5 °C (based on 532 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00335 - 0.01640), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.0 se; based on diet studies.
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).
Nutrients (Ref. 124155):  Calcium = 165 [80, 291] mg/100g; Iron = 0.868 [0.480, 1.563] mg/100g; Protein = 17.9 [16.7, 19.1] %; Omega3 = 0.0751 [, ] g/100g; Selenium = 20 [9, 47] μg/100g; VitaminA = 114 [27, 469] μg/100g; Zinc = 2.71 [1.75, 4.02] mg/100g (wet weight);
