Maturity: Lm ?, range 24 - ? cm
Max length : 70.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2272); common length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 6871)
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).
生活于近海与被范围从潮间带到 240 公尺深的外海.(参考文献 9910,12951) 发现埋藏于沙与泥底部; 有时发现搁浅的离开水面被潮水但是能够被存活长达数小时之久。 (参考文献 9910) 吃螃蟹,蠕虫与鱼。 卵胎生的.(参考文献 50449) 使用它的发电器打昏猎物的一个缓慢移动的种。 当偶然地踏到或摸到,也打昏人。 (参考文献 9910) 可能对 92 公分TL 的最大长度.(参考文献 9910)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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。
