Maturity: L_m ?, range 24 - ? cm
Max length : 92.0 cm TL macho/indeterminado; (Ref. 3290); common length : 55.0 cm TL macho/indeterminado; (Ref. 3290); Idade máx. registada: 6 anos (Ref. 52060)

Inhabits coastal waters, as well as estuaries and tidal rivers. Feeds mainly on invertebrates and small fishes. The sharp dorsal and pectoral fin spines can inflict painful wounds. Sold mostly fresh and dried-salted in markets.

Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 28.1, mean 27.3 °C (based on 111 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00458 - 0.01258), b=3.09 (2.94 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 4.0 ±0.61 se; based on food items.

Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.36; tm=2; tmax=6).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).

Categoria de preço (Ref. 80766): Medium.
