生物學特性     字彙 (例如 epibenthic)

Demersal on both insular and continental shelves, but now thought to be extinct through much if its original range (Ref. 114953). Inshore and intertidal species known to enter freshwater in some areas (Ref. 9859). Found in shallow bays, estuaries, and lagoons (Ref. 11228). Often on the bottom with its saw elevated at an angle to the body axis (Ref. 9859). Feeds on fishes and shellfishes (Ref. 58784). Ovoviviparous (Ref. 50449). Reaches maturity after 9 years. Females have litters of approximately 12 pups. Maturity size unclear, possibly near 430 cm TL; born at approximately 80 cm TL (Ref. 114953). Flesh considered tasty (Ref. 11228).

知道的沿海地區與潮間帶的種在一些地區進入淡水.(參考文獻 9859) 發現於淺灣,河口與潟湖.。 (參考文獻 11228) 時常在底部上用它的鋸子升高的以一個角到體軸.(參考文獻 9859) 捕食魚類與貝.(參考文獻 58784) 卵胎生的.(參考文獻 50449) 肉被認為是好吃的.(參考文獻 11228)
