Biologie     Verklarende woordenlijst (bv. epibenthic)

Found on the outer continental shelf, around rocks, in kelp beds, over fine sand bottoms or buried in sand. Solitary, nomadic, and can remain suspended in the water with minimal swimming (Ref. 12951). Feeds on bony fishes, mainly herrings and halibuts. Ovoviviparous (Ref. 50449). Produces litters of up to 17 pups. Males reaches maturity at ca. 65 cm TL, females at ca. 73 cm TL (Ref. 114953). Attacks their prey from the substratum by day and actively forage at night with the aid of its electric organ discharge or EOD (Ref. 10011). The EOD of a large individual was measured at 50 V; with a low internal organ resistance the power output exceeded 1 kW (Ref. 10480). Aggressive when provoked but no human has yet been injured by the electric shock (Ref. 2850). Does not do well in aquariums (Ref. 12951).

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). Reproductive cycle appears to be annual in males and biannual in females (Ref. 48844). No defined birthing season (Ref. 48844).
