Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 18 - 20; Spine anali: 2; Raggi anali molli: 18 - 21. Head and body greyish brown with small white spots; median fin with white dots. Dorsal fin deeply notched; segmented caudal rays usually 13-14, branched middle 6-9; pinnately branched supraorbital tentacle; lacking nape cirri; posterior rim of anterior nostril with small cirrus, typically unbranched; upper and lower lip margins smooth; with occipital crest (higher in males); last dorsal ray and caudal peduncle connected by membrane; elongate body, depth at anal-fin origin ca. 7.7-7.9 in SL. Maximum size to 9 cm TL (Ref. 90102).

Biologia     Glossario (es. epibenthic)

Facultative air-breathing (Ref. 126274); Adults inhabit exposed rocky shores (Ref. 90102). 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).

Estimates based on models

Preferred temperature (Ref. 123201): 27.1 - 29.3, mean 28.8 °C (based on 1167 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
