背棘 (总数) : 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).
Body shape (shape guide): elongated.
一个象鱼具有一个像锄头一样的吻与弓形的尾鳍.(参考文献 5578) 银色或青铜色在侧面与头部上有褐色的斑纹; 鳍设圈套褐色。 (参考文献 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.
