Found on the continental and insular shelves, often occurring in shallow water close inshore. Prefers estuaries and shallow bays, especially sandy and algal-covered areas and eelgrass flats. Feeds on small fishes and probably crustaceans and other benthic invertebrates. Often solitary, though some may cluster in resting areas on bottom. Ovoviviparous (aplacental), with 10 to 20 young in a litter. Meat is regarded as of inferior quality.
栖息于大陆架与岛屿棚了, 时常出现在浅水区近岸。 偏爱河口与浅湾，尤其沙的与被海藻覆盖区域与鳗草平坦的。 吃小鱼与可能甲壳动物与其他的底栖无脊椎动物。 时常独居性的, 虽然一些可能聚集于让在底部上的区域休息。 卵胎生的 (无胎盘的),10 到 20 幼鱼在一胎。 肉被视为低品质。
