Maturity: L_m ? range ? - ? cm
Max length : 76.0 cm TL macho/indeterminado; (Ref. 2850); common length : 45.0 cm TL macho/indeterminado; (Ref. 9261)

Common in inshore waters from approximately 15 m and in shallow bays, sometimes in deep water (Ref. 2850, Ref. 114953). Feeds on small benthic invertebrates, polychaete worms and shrimps (Ref. 114953). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 7.0-8.5 cm long and 6.5-7.6 cm wide (Ref. 41300). Males reaches maturity at ca. 47 cm TL, females at 52 cm TL; young hatch at ca. 15-23 cm TL (Ref. 114953).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 5.3 - 14.2, mean 7.5 °C (based on 42 cells).

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

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Categoria de preço (Ref. 80766): Medium.
