Short description Chiavi di identificazione | Morfologia | Morfometria

Dorsal rays IX,12; anal rays III,12; pectoral rays 13. Lateral-line scales 20 + 5. Head naked except for one or two small partly embedded scales dorsally on opercle. Gill rakers 16-18. Body depth 2.6-2.75 in SL. Dorsal profile of snout forming an angle of about 50°, front of head with a slight median ridge. Origin of the dorsal fin a little posterior to preopercular margin; first dorsal spine flexible, slightly longer than second spine, 4.05-4.15 in head length; space between first two dorsal spines two-thirds space between second and third spines. Caudal fin slightly rounded. Pectoral fins short, 1.6-1.7 in HL. Body bright red, edges of scales darker red; membranes of spinous portion of dorsal fin bluish gray, each with a black spot; each of first three membranes of soft portion of fin with a faint black spot (Ref. 57578).

Estimates based on models

Preferred temperature (Ref. 123201): 11.8 - 12.2, mean 12 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00397 - 0.02640), b=3.06 (2.84 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

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).
