The Australian numbfish or the coffin ray (Hypnos monopterygius), is native to Australia’s waters. It loves sandy and muddy habitats of inshore water. Like other rays, the coffin ray is sluggish, nocturnal, exhibits viviparity, and produces a powerful electric shock in defense and attack mode. Alternatively, the coffin ray can also be recognized by its extremely shorter tail, enlarged pectoral fin, diminutive dorsal, and caudal fins in its posterior giving it a pear-like shape. The fish is a representative of the family Hypnidae possessing tiny eyes, but with a large distensible mouth and brown coats.
