Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 2; Raggi anali molli: 11 - 12; Vertebre: 26. Body very dark gray-brown, depth 1.95-2.1 in SL. Caudal fin abruptly white. Narrow posterior part of dorsal and anal fins hyaline. Base of pectoral fins with a large black spot. Upper and lower spiniform procurrent caudal rays 2; upper and lower 2 branched caudal rays filamentous and often very long. Tube lateral line scales 16-18, rarely 16. Free margin of subopercle nearly reaching a vertical at rear margin of pupil.

Biologia     Glossario (es. epibenthic)

A shallow water species. Feeds on planktons (Ref. 89972). Diurnal species (Ref. 54980). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 27.6 - 29, mean 28 °C (based on 103 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00940 - 0.04644), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.2 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).
Nutrients (Ref. 124155):  Calcium = 179 [86, 319] mg/100g; Iron = 1.06 [0.59, 1.86] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.128 [0.066, 0.236] g/100g; Selenium = 20.5 [9.5, 44.6] μg/100g; VitaminA = 185 [51, 661] μg/100g; Zinc = 2 [1, 3] mg/100g (wet weight);
