Found on the continental shelf, especially abundant off river mouths on muddy bottoms. Salinity: 35-36 ppt. Oxygen: 3-4 ppm. Feeds on small bottom and littoral organisms like crustaceans, bony fishes, octopi and sponges. Viviparous (Ref. 50449), with 7 young in a litter (Ref. 244). Dental sexual dimorphism is manifested by males having greatly enlarged anterior teeth. Utilized fresh, smoked or dried salted for human consumption, skin for leather.
棲息於大陸棚，尤其豐富的河口外的沙泥底上了。 鹽度: 35-36個 ppt。 氧: 3-4個 ppm。 吃小的底部與海濱的生物例如甲殼動物，硬骨魚類，章魚與海綿。 胎生的 (參考文獻 50449),7 幼魚在一胎.(參考文獻 244) 牙齒的性同種二形是由雄性顯示，有明顯增大前面的齒。 生鮮使用, 煙燻了或乾燥鹽醃供人類消費，皮膚用做皮革。
