Short description Claves de identificación | Morfología | Morfometría

Long, flat, rounded snout like a duck's bill; head thick and pectoral disc with sharply curved, angular corners; upper or lower jaw; usually with 7 rows of flat teeth (Ref. 5578). Light brown with several pale blue-grey stripes (may be absent) dorsally, white ventrally (Ref. 5578).

Found in coastal tropical and warm temperate waters, occasionally offshore. Sometimes found in small groups (Ref. 5578). Feed on bottom-living crustaceans and mollusks. Ovoviviparous (Ref. 50449), aplacental (Ref. 57025). Prized angling fish, often released (Ref. 5578). Flesh highly esteemed (Ref. 3965).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Gestation about 6 months; 3-7 young produced (Ref. 5578). Size at birth 45 cm WD (Ref. 6677).

Estimates based on models

Preferred temperature (Ref. 123201): 13.7 - 24.5, mean 17.2 °C (based on 196 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00123 - 0.01235), b=3.08 (2.82 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.57 se; based on food items.

Resiliencia (Ref. 120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Fec=3).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (83 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 6.08 [0.77, 110.95] mg/100g; Iron = 0.496 [0.044, 5.834] mg/100g; Protein = 20.6 [15.3, 25.8] %; Omega3 = 0.146 [0.059, 0.340] g/100g; Selenium = 32.5 [6.1, 179.7] μg/100g; VitaminA = 3.64 [0.33, 39.75] μg/100g; Zinc = 0.455 [0.027, 5.132] mg/100g (wet weight); based on nutrient studies.
