Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 22 - 25; Raggi dorsali molli (totale) : 11 - 14; Spine anali: 2; Raggi anali molli: 23 - 26; Vertebre: 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).

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).

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

Estimates based on models

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).
