Occurs inshore and offshore, ranging from the intertidal to 240 m depth (Ref. 9910, 12951). Found buried on sand and mud bottoms; sometimes found stranded out of water by the tide but is capable of surviving for hours (Ref. 9910). Feeds on crabs, worms, and fishes. It was reported that larger fishes, similar size to themselves have been found in the stomachs of Coffin rays, ingested whole through the large gape (Ref. 114953). Ovoviviparous (Ref. 50449). Maximum length probably to 92 cm TL (Ref. 9910). Both sexes mature at 40-48 cm TL; born at ca. 8-11 cm TL (Ref. 114953). A slow-moving species which uses its electric organs to stun prey. Also stuns people when accidentally stepped upon or handled (Ref. 9910).
生活於近海與被範圍從潮間帶到 240 公尺深的外海.(參考文獻 9910,12951) 發現埋藏於沙與泥底部; 有時發現擱淺的離開水面被潮水但是能夠被存活長達數小時之久。 (參考文獻 9910) 吃螃蟹,蠕蟲與魚。 卵胎生的.(參考文獻 50449) 使用它的發電器打昏獵物的一個緩慢移動的種。 當偶然地踏到或摸到,也打昏人。 (參考文獻 9910) 可能對 92 公分TL 的最大長度.(參考文獻 9910)

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). Size at birth 8 to 11 cm TL (Ref. 9910).印度-西太平洋: 澳洲的特有種。
