Biologia     Glossário (ex. epibenthic)

Sublittoral on sandy mud bottoms (Ref. 11230). Depth range given by H. Ishihara (pers.comm. 07/07). Feed on invertebrates and bony fishes (Ref. 9908). 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 4.9-5.4 cm long and 2.5-2.9 cm wide (Ref. 41249, 41253).

Estimates based on models

Preferred temperature (Ref. 123201): 13.8 - 23.7, mean 21.1 °C (based on 46 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).
Nível Trófico (Ref. 69278):  4.0   ±0.62 se; based on food items.
Generation time: 7.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
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 (54 of 100).
Nutrients (Ref. 124155):  Calcium = 17.6 [3.0, 82.8] mg/100g; Iron = 0.296 [0.079, 0.831] mg/100g; Protein = 17.2 [14.5, 19.8] %; Omega3 = 0.975 [0.309, 3.534] g/100g; Selenium = 7.51 [2.32, 23.13] μg/100g; VitaminA = 21.4 [6.5, 67.6] μg/100g; Zinc = 0.54 [0.26, 0.98] mg/100g (wet weight);
