The gummy shark or Dogfish (Mustelus antarcticus), or manga of the Maoris, comes into very shallow water at night and is frequently encountered on mud flats. It grows up to 3 ½ ft in length and is ashy grey with lighter spots on the back. It is easily recognised by its small blunt teeth, arranged like a pavement, which renders it inoffensive to man. The Maoris of old relished the sun-dried flesh of this and other small sharks.
