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 4,000 metres (2,600 and 13,100 ft). Its adult length is 20 to 40 centimetres (8 to 16 in), although Fishbase [ 2 ] gives lengths up to 1 metre (3 ft 3 in).
The common Atlantic grenadier is blue-violet in colour, with silvery and black areas. Its maximum length is 36 centimetres (14 in). It has 2 dorsal spines and its spinules are lanceolate or shield-shaped. [7] Its head, snout and chin barbel are short. [8] [9]
The graceful grenadier (Hymenogadus gracilis) is a species of rattail fish. It is found at depths of 160–345 m (525–1,132 ft) in tropical and subtropical seas worldwide. [ 1 ] This is one of the smallest of the rattails, growing to no more than 13 cm (5.1 in) in length.
The deepwater grenadier is very large for its genus, measuring up to 129 cm (4.23 ft) and 14 kg (31 lb). [8] Olfaction and taste are important senses for finding prey, which is unsurprising as it lives in the near-total darkness of the deep sea. [9] [8] It has a swim bladder, showing that it is a mobile forager. [10]
Günther's grenadier has a measurement of up to 50 cm (20 in). [9] The head is compressed, with large eyes; the body is generally brownish, with the mouth and gill cavity darker. [ 9 ]
