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 roughnose grenadier (Trachyrincus murrayi) is a species of fish in the subfamily Macrourinae (rat-tails). [ 3 ] [ 4 ] The species is named for Sir John Murray . [ 5 ]
Macrourus berglax, also known as the roughhead grenadier or onion-eye grenadier, is a species of marine ray-finned fish in the family Macrouridae. It is a deep-water fish found in the Atlantic Ocean .
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 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 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 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 ...
