Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 0; Anale stekels 0; Anale zachte stralen: 0. A medium-sized spindle-shaped shark with very large eyes lacking a nictitating membrane, long gill slits extending onto dorsal surface of head, lanceolate teeth, weak keel and precaudal pits on caudal peduncle (Ref. 6871, 43278). Small and low dorsal fins, with second dorsal fin less than half the size of the first but larger than the anal fin (Ref. 6871). Pectoral fin broad and rounded (Ref. 6871). Light or dark grey above, paler below, fins white-edged, sometimes with small white spots on body and a white blotch between mouth and gill slits (Ref. 13569).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

An oceanic species usually found offshore and far from land but sometimes occurring inshore (Ref. 9993, 43278, 58302). Epi- and mesopelagic, with occasional near-bottom occurrences (Ref. 43278, 58302). Although considered not dangerous to people, its powerful jaws, jaw muscles and teeth invite respect. Flesh not appreciated and therefore the catch is usually discarded (Ref. 247); utilized for its large, squalene-rich liver (Ref. 9993). Feeds on small pelagic bony fishes, squids and shrimps (Ref. 5578). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). With 4 young in a litter, born at 40 to 43 cm TL (Ref. 12288). Maximum length for female given in Romanove et.al 1994 (Ref. 44781). Common bycatch of tuna longline fisheries, and occasionally tuna gillnet fisheries (Ref.58048).

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

Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). With 4 young in a litter, born at 40-43 cm (Ref. 11228).
