Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 9; Raios dorsais moles (total) : 12 - 13; Espinhos anais: 3; Raios anais moles: 11 - 12. Diagnosis: pectoral fin with 4 threadlike filaments (Ref. 57402, 81658). Pectoral fin inserted very low on body, generally somewhat longer than upper part of fin (Ref. 57402).

Occurs in shallow coastal waters, over sandy and muddy bottoms, sometimes in brackish habitats (Ref. 57343, 81658).

Estimates based on models

Preferred temperature (Ref. 115969): 22.3 - 28, mean 26 (based on 48 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00510 - 0.00855), b=3.09 (3.03 - 3.15), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 4.0 ±0.66 se; based on food items.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.34-0.41; assuming tm=3-4).

Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 3 data-limited stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (87 of 100).

Categoria de preço (Ref. 80766): High.
