Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Bathydemersal to benthopelagic generally between 300 and 500 m depth. Found in the upper continental slope. Usually found in deeper waters in southern latitudes, while making a summer inshore migration up to 40-100 m in the northern areas. Sluggish, usually occurring in small groups. Feeds mainly on bottom-living invertebrates. The single dorsal spine is sharp and pointed, and although only mildly venomous can inflict a painful wound. Oviparous. Males have a clasper on the forehead that is probably used to hold on to the female during copulation. Egg capsules are about 17 cm long; young look alike adults and hatch when 10 cm long. Common by-catch when trawling for shrimps in the North Sea or Skaggerak.
Oviparous; egg-capsules slender, club-shaped with narrow lateral membranes and a horny filament at the long pointed end, 17 cm long and 3 cm wide; deposited mainly in spring and summer. The embryos developing in about 9-12 months and hatch at 10 cm length.
