Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found in mangrove areas, also over sand or sand and rubble in lagoons near reefs to depth of 85 m on the continental shelf (Ref. 9840). Feeds on small fishes, bottom dwelling crustaceans, and large infauna (Ref. 9840). Ovoviviparous (Ref. 50449), with histotrophy. Caught regularly, but in low numbers, by demersal tangle net and bottom trawl fisheries. Utilized for its meat, skin (high value) and cartilage (Ref.58048).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

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). Distinct pairing with embrace (Ref. 205). Fully developed young, size at birth 28 cm (Ref. 37816, Ref.58048).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 25.5 - 28.8, mean 27.7 (based on 584 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00555 - 0.05444), b=3.03 (2.78 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.64 se; Based on food items.
Widerstandsfähigkeit (Ref. 69278):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).
Verwundbarkeit (Ref. 59153):  Very high vulnerability (86 of 100) .
Preiskategorie (Ref. 80766):   Low.
