The unusual pear -like shape of the coffin ray distinguishes it from all other rays. Its body is flabby, with the two large, kidney -shaped electric organs visible on both sides of the head.

| IUCN_Threat_status: | Not assessed |
| Habitat: | Moderately exposed sand |
| Description: | The coffin ray has a distinctive double-lobed shape with very short tail. The species should be well known to most NSW and WAdivers because of the severe electric shock produced on contact. In many cases, divers receive shocks when placing a hand on apparently bare sand—the only sign of a concealed ray is its two fringed nostrils open at the sediment surface |
