Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 15 - 17; Raggi dorsali molli (totale) : 10 - 13; Spine anali: 3; Raggi anali molli: 9 - 10. Diagnosis: low number of gill-rakers (15-18) (Ref. 55925).

Occurs in shallower part of the sandy shores but also found at levels below 30m (Ref. 5595), and frequents muddy/soft bottoms (Ref. 5595, 55925), but also found over rocky habitat (Ref. 55925). Feeds mainly on small benthic invertebrates (Ref. 267). Scoops up large amounts of silty sediment from the sand; commonly observed in small groups of about 5 individuals, but also forages in large schools (Ref. 55925).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 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).

Price category (Ref. 80766): Unknown.
