Grenadiers or rattails are generally large, brown to black gadiform marine fish of the subfamily Macrourinae, [1] the largest subfamily of the family Macrouridae. Found at great depths from the Arctic to Antarctic , members of this subfamily are amongst the most abundant of the deep-sea fish.
Coryphaenoides rupestris is a species of marine ray-finned fish in the family Macrouridae. Its common names include the rock grenadier, the roundnose grenadier and the roundhead rat-tail. In France it is known as grenadier de roche and in Spain as granadero de roca. It is a large, deep-water species and is fished commercially in the northern ...
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 blue grenadier (also known as hoki, blue hake, New Zealand whiptail, or whiptail hake, Macruronus novaezelandiae) is a merluccid hake of the family Merlucciidae found around southern Australia and New Zealand, as well as off both the Atlantic and Pacific coasts of South America from Peru to Brazil [1] at depths of between 10 and 1,000 m (33 and 3,300 ft).
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 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]
The Mediterranean grenadier has a measurement of up to 73 cm (29 in). [6] The head is scaled except for its gular and branchiostegal membranes; it has a blunt snout. [7] [8] Its brain shows increased volume in the octavolateral area (premotor organization of body movements) and gustatory area (taste); this is unsurprising as it lives in near-total darkness and is dependent on chemosensory ...
The ridge scaled rattail [2] or ridge-scaled grenadier, [3] Macrourus carinatus, is a species of deep-water fish in the family Macrouridae. [1] [2] It has southern circumglobal distribution in temperate to subantarctic waters (34°S–65°S) and is found in the Southern Atlantic, Indian and Pacific Oceans and in the Southern Ocean [1] [2] at depths of about 200–1,200 m (660–3,940 ft).
