Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0. An angelshark with large thorns on snout and above eyes but not on midback, weakly bifurcated nasal barbels and weakly fringed anterior nasal flaps, the first dorsal-fin origin usually well behind the rear tips of pelvic fin, and prominent white spots on body (Ref. 247)

Biologi     Ordlista (t.ex. epibenthic)

Found on sand and mud bottom (Ref. 26999) of continental shelves and upper slopes (Ref. 247). Mostly between 50 and 100 m but deeper in the tropics (Ref. 247). Feeds on small fishes (Ref. 247). Ovoviviparous (Ref. 50449). Utilized fresh and dried salted for human consumption; liver oil and hide also used (Ref. 247).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Size at birth about 24 to 27 cm TL (Ref. 247).
