Olive-green, yellow or dark brown dorsally with pale blue or grey markings; white ventrally (Ref. 26346). No caudal fin (Ref. 26346).
Occurs in bays, estuaries, and near rocky reefs (Ref. 12951). Usually solitary (Ref. 12951). Feeds on clams, oysters, worms, and crabs (Ref. 12951). Ovoviviparous (Ref. 50449). Although the spine on the tail is capable of inflicting a painful wound, the poison is quickly neutralized by immersion of the injured area in hot water (Ref. 26346).

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). Young are born at less than 50 cm (Ref. 26346).
