Biology

englanti
)
tarjonnut Fishbase
Found in relatively cold coastal waters and on upper parts of continental slopes (Ref. 3167). Most common at depths of around 200 m, but deeper in southern areas (Ref. 3167). Feed on all kinds of bottom animals, probably preferring fish (Ref. 3167). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 7.5-9.9 cm long and 4.5-4.7 cm wide (Ref. 41250). Maximum length for female is 111 cm (Ref. 41333).
