简单描述
型态特徵 | 形态测量图
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).
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.
从近岸与浅湾到斜坡发现了。 (参考文献 5578) 吃小鱼与各式各样的无脊椎动物。 (参考文献 27121) 商业地贩卖当 '银色的吹喇叭'(参考文献 3180) 而且在非洲南部中被认为是一个佳肴.(参考文献 27121) 卵生的.(参考文献 50449) 产生卵荚那是纱锭形状的, 有宽的水平凸缘.(参考文献 36731) 最小深度记录自了参考文献 7403.
