Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 22 - 25; Dorsal soft rays (total): 11 - 14; Anal spines: 2; Anal soft rays: 23 - 26; Vertebrae: 40 - 43. This species is distinguished by the following characters: 1-2 pairs of large iridescent blue spots on the upper lip; relatively small body size; 2 common pores (sensory pores between the mandibular and preopercular series); a closed wedge of spines on the posterior part of the frontal; 2 rows of interorbital spines, the outer one continuous; D XXII-XXV,11-14 (35-37 total dorsal-fin elements; A II,23-26 (Ref. 81029).

Biology     Glossary (e.g. epibenthic)

A small benthic reef fish which is common in shallow water, but also occurs to depths of at least 31 meters (Ref. 81029). Oviparous (Ref. 56066). Eggs are attached to the walls of the parent's shelter and are brooded by the male parent (Ref. 56066).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Oviparous (Ref. 56066). Males guard the eggs until they hatch (Ref. 56066).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00183 - 0.01143), b=3.08 (2.86 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
