Korte beschrijving
Morfologie | Morfometrie
Dark grey dorsally, white ventrally (Ref. 26346).
Found on the continental shelf and upper slope (Ref. 26346). Feeds on fish, probably at night (Ref. 26346). Ovoviviparous (Ref. 50449).
Levenscyclus en paargedrag
Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | 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).
