Tamanho / Peso / Idade

Maturity: L_m ? range ? - ? cm
Max length : 113 cm TL macho/indeterminado; (Ref. 114953)

Found on sand-mud bottoms (Ref. 41299). Depth range from 80 m-150 m (Ref. 41299). Feeds on invertebrates and bony fish (Ref. 9908, 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 8.5-10.0 cm long and 5.5-6.4 cm wide (Ref. 41249 , 41253).

Estimates based on models

Preferred temperature (Ref. 123201): 14 - 27.2, mean 20.3 °C (based on 96 cells).

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

Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

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

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100).
