Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 45.0 cm TL macho / no sexado; (Ref. 106604)

Bottom-dwellers that feed on invertebrates and bony fish (Ref. 9908). Depth range given by H. Ishihara (pers.comm. 07/07). 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 5.3-6.7 cm long and 2.7-3.9 cm wide (Ref. 41253, 41298).

Oviparous (Ref. 9908). 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): 18.4 - 26.8, mean 25.2 °C (based on 82 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [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).

Nivel trófico (Ref. 69278): 4.0 ±0.61 se; based on food items.

Generation time: 2.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).

Price category (Ref. 80766): Medium.
