Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 7. This species is distinguished by the following characters: concave bony interorbital is less than half pupil-diameter in width; with a slight or no groove posterodorsal to the eye; scales in the midline of the predorsal 8-10; anal-fin rays 7; the fifth pelvic ray is branched twice dichotomously and subequal to the fourth in length, with a full basal membrane; the epaxial musculature reaches anteromedially to a point in line with the posterior margin of the pupil in adults; scale pockets on the head and body are strongly outlined by brown chromatophores (Ref. 100726).

Species collected from jetty pilings, log debris, and concrete stairs at the water’s edge, at about 1-4 meters. It apparently have an affinity for sponge-encrusted surfaces, but the general area where it is observed is characterized by extensive silty mud substrata inhabited by a large number of burrowing gobies. It was not previously observed despite nearly 100 hours of scuba-diving because the collection site is immediately adjacent to shore at a busy shipyard where diving is usually banned during daylight hours. Most of the specimens were found on the inner side of a single pillar of the jetty, which was situated in total shade (Ref. 119492).

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=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
