ການຈະເລີນເຕັມໄວ: Lm ?, range 24 - ? cm
Max length : 70.0 cm TL ຕົວຜູ້/ບໍ່ມີເພດ; (Ref. 2272); common length : 40.0 cm TL ຕົວຜູ້/ບໍ່ມີເພດ; (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).

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).
