The Australian Numbfish, also known as the coffin ray, or numbray, is an electric ray that is found within Australian waters up 80 meters deep.
Australian Numbfish can reach up to 40cm in length and is shaped a bit more rounded than other rays. They have a small tail at the end, and two eyes at the front, with the two rounded sections that give the Numbfish its pear like shape.
Normally nocturnal creatures, Australian Numbfish can be found burrowed in sand and mud during the day, coming out at night to hunt. As the name suggests, they are electric, providing a numbing jolt of up to 200 volts if agitated which, while not fatal to humans, can be a severe shock. Quite the fearless critter: it regularly feeds on fish that are bigger or the same size of itself.
It has been seen by divers at the Glenelg Dredge, Seacliff Reef and near Whyalla.
