The Blind legged torpedo, Blind electric ray, or Numbfish, (Typhlonarke aysoni), is a numbfish of the genus Typhlonarke, found around New Zealand from Cook Strait southwards on the continental shelf, at depths of between 100 and 900 metres. Its length is between 15 to 30 centimetres.
The Blind legged torpedo is a very small electric ray with the typical round body shape and small fleshy tail. A large part of the front of the body is taken up with modified muscle organs that store up electrical charge and delivery it to stun prey when needed. This mechanism can also be used for navigation and prey detection in dark or murky water.
The Blind legged torpedo is dark brown in colour.
