Biologie     Verklarende woordenlijst (b.v. epibenthic)

Occurs off sandy beaches, rocky shores and in shallow bays (Ref. 5578). Feeds on crabs, lobsters, bony fish and small sharks (Ref. 5578). Ovoviviparous (Ref. 50449). Forms schools in summer (Ref. 244). Hardy and keeps well in captivity (Ref. 244). Commonly caught by rock and surf sports anglers but not eaten much (Ref. 244). Meat is dried into shark 'biltong' or jerky which commands a relatively high price (Ref. 244). Attains 160 cm, TL (Ref. 36731).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Ovoviviparous, embryos feed solely on yolk (Ref. 50449), with 6 to 12 young in a litter (Ref. 244). 30-32 cm at birth (Ref. 244).

Estimates based on models

Preferred temperature (Ref. 115969): 15.8 - 22.4, mean 19.3 °C (based on 26 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00118 - 0.00585), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.5 se; based on diet studies.
Weerstandsvermogen (Ref. 120179):  zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec=6).
Kwetsbaarheid (Ref. 59153):  High to very high vulnerability (74 of 100) .
Prijsklasse (Ref. 80766):   High.
