Commonly found in sandy and muddy bays and sloughs, also on rocky bottom and in kelp beds (Ref. 2850). Sometimes buries itself in sand (Ref. 2850). Found singly or in schools (Ref. 12951). Feeds on bivalves, snails, polychaetes, shrimps, and crabs (Ref. 9257). Ovoviviparous (Ref. 50449). Venomous spine on tail. Not fished commercially, but shows up as by-catch species (Ref. 9257).
Life cycle and mating behavior
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).
