Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 18-20; Anal spines: 2; Anal soft rays: 20 - 21. Body with 6-7 irregular bands (Ref. 4404). Dark spot present distally on anterior part of dorsal fin; females with dark spots on vertical fins, males more evenly colored (Ref. 4404).

Biology     Glossary (e.g. epibenthic)

Inhabit shallow shore line water of intertidal reef flats from 0.5 to 1.5 m depth where the substrate consists of a thin carpet of algal turf and sand (Ref. 205). Benthic (Ref. 58302). 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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 23.6 - 29.3, mean 27.5 (based on 1314 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00343 - 0.01679), b=3.03 (2.84 - 3.22), in cm Total Length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
