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.
棲息於大陸棚與島嶼棚了, 時常出現在淺水區近岸。 偏愛河口與淺灣，尤其沙的與被海藻覆蓋區域與鰻草平坦的。 吃小魚與可能甲殼動物與其他的底棲無脊椎動物。 時常獨居性的, 雖然一些可能聚集於讓在底部上的區域休息。 卵胎生的 (無胎盤的),10 到 20 幼魚在一胎。 肉被視為低品質。
