The abyssal grenadier, Coryphaenoides armatus, is an abyssal fish of the genus Coryphaenoides, found in all the world's oceans, at depths between 800 and 5,493 metres (2,625 and 18,022 ft). Its adult length is 20 to 40 centimetres (8 to 16 in), although Fishbase gives lengths up to 1 metre (3 ft 3 in). The abyssal grenadier's body is unique in that it contains two dorsal spines and about 124 dorsal soft rays, which are the flexible jointed rays supporting a fin nearest to the back in the spinal column.
