Descripción breve
Claves de identificación | Morfología | Morfometría
Grey with scattered charcoal blotches dorsally, greyish-white ventrally (Ref. 26346).
Body shape (shape guide): other.
Occurs in coastal waters, continental shelf and upper slope (Ref. 26346). Usually found in deeper waters to 200 m (Ref. 9258). Mainly feeds on benthic decapods and bony fishes (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 150 cm TL. This species is said to be long lived and slow growing (Ref. 114953).
