Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 12 - 14; Radios blandos dorsales (total) : 19 - 22; Espinas anales: 2 - 3; Radios blandos anales: 20 - 23; Vértebra: 37 - 40. Diagnosis: Dorsal fin XII-XIV, 19-22, notched between spinous and segmented-ray portions; anal fin II-III, 20-23 (rarely 23); pectoral rays 12-15 (usually 14); pelvic fin I, 3; caudal fin procurrent rays 10-16, segmented rays 13. Vertebrae 10-12 + 26-29. Last pleural rib on 11-13th vertebrae. Orbital cirrus simple filamentous; nasal cirri short and simple to palmate with 2-7 branches; nape without cirri. Lateral line, continuous anterodorsally below dorsal spines from 6-7th to 10th, disconnected posteroventrally up to below dorsal spine 9-13th. Mandibular pores 3-7 Lips margin entire. Occipital crest present, higher in males (Ref. 9962). Body depth at anal-fin origin 5.8-7.3 in SL. Male crest yellow; body greyish, shading ventrally to white, with 9 brown or olive vertical bars on side, and some horizontal streaks on middle of body (Ref. 90102). Females have numerous longitudinal pinstripes on their sides and black specks on their fins while males have dark patches and small blue spots on their sides (Ref. 37816).

Biología     Glosario (por ej. epibenthic)

Adults inhabit exposed shallow shores (0-3 m) and often found in tidepools (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. 115969): 26.7 - 29.4, mean 28.7 (based on 908 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00335 - 0.01640), b=3.02 (2.83 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  2.8   ±0.3 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
