Pelorus Jack was approximately 4 metres (13 ft) long and was of a white color with grey lines or shadings, and a round, white head.
 Although its sex was never determined, it was identified from photographs as a Risso's dolphin, Grampus griseus.
 This is an uncommon species in New Zealand waters, and only 12 Risso's dolphins have been reported in that area.
