Short description Morfologia | Morfometria

Spine dorsali (totale): 7; Raggi dorsali molli (totale): 9; Spine anali 1; Raggi anali molli: 8. This species is distinguished by the following combination of characters: D VI + I,9, with the second dorsal-fin spine usually with short filament, when adpressed extending to the base of first to fourth segmented dorsal-fin ray; A I,8; the fifth segmented pelvic-fin ray with sequential branching consisting of three branch points, its length 76.9-87.5% (mean 83.4%) length of fourth ray; the basal membrane of pelvic fin is fully developed; gill rakers on first arch 3-4 + 12-13; opercle scaleless; posterior naris is large and adnate to orbital rim. Colour in life mainly orange to brownish red with diffuse brown scale margins that form a reticulated pattern; indistinct narrow white or gray bars (sometimes branching) along back and dorsalmost part of caudal peduncle; the pectoral-fin base with distinctive orange to reddish-brown medial area with large white spots dorsally and ventrally (Ref. 119492).

Biologia     Glossario (es. epibenthic)

Species collected from jetty pilings, log debris, and concrete stairs at the water’s edge, at about 1-4 meters. It seems to 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. 82805):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00261 - 0.01268), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
