Size / Weight / Age

Maturity: Lm 67.0, range 57 - 77 cm

Short description Morphology | Morphometrics

Vertebrae: 149 - 150. Spiral valve count: 8-10. Broad disc is about as wide as it is long; dorsal surface covered with numerous, small to large, scattered, stellate prickles; a single median row of enlarged thorns running along the mid-back; a broad, short snout; small, blunt, pebble like teeth; a dorsal fin that originates closer to the pelvic fin bases than to the caudal fin origin; a thick tail and a moderately large, rounded caudal fin without a distinct lower lobe. Tooth count: 60-75/60-75. Coloration: The dorsal surface is sandy brown to dark gray, with several prominent black bars, and lighter below with dark spots on the posterior edge of the pectoral fins.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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). During breeding season, male and female adult schools congregate in shallow areas of bays and lagoons (Ref. 51576). Parturition takes place three to four months after mating, with litters of 4 to 11 pups (Ref. 48844).

Estimates based on models

Preferred temperature (Ref. 123201): 18.1 - 28.5, mean 23.1 °C (based on 64 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00267 - 0.01964), b=3.00 (2.77 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.53 se; based on food items.
Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Fec = 4).
Nutrients (Ref. 124155):  Calcium = 15 [3, 53] mg/100g ; Iron = 0.612 [0.152, 1.670] mg/100g ; Protein = 19.5 [17.3, 21.6] % ; Omega3 = 0.146 [0.068, 0.295] g/100g ; Selenium = 14.8 [3.6, 43.0] μg/100g ; VitaminA = 35.2 [10.7, 108.4] μg/100g ; Zinc = 0.717 [0.330, 1.883] mg/100g (wet weight);
