Found from close inshore and shallow bays to the slope (Ref. 5578). Feeds on small fish and a wide variety of invertebrates (Ref. 27121). Oviparous (Ref. 50449). Produces egg-cases that are spindle shaped, with broad horizontal flanges (Ref. 36731). This species is known to host on its gills monogenean parasites Callorhynchocotyle callorhynchi (Manter, 1955) (Hexabothriidae) and Callorhynchicola multitesticulatus Manter, 1955 (Chimaericolidae) on its gills (Ref. 124045, 124046). Sold commercially as 'silver trumpeter' (Ref. 3180) and considered a delicacy in southern Africa (Ref. 27121). Minimum depth reported from Ref. 7403.
