Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 1. An elephant fish with a hoe-like snout and arched caudal fin (Ref. 5578). Silvery or bronzy with brown markings on flanks and head; fin webs brown (Ref. 5578).
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.
