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 roughhead grenadier feeds on crustaceans and other small invertebrates it finds on the seabed. The diet includes small fish, shrimps, amphipods, polychaete worms, bivalve molluscs, isopods, brittle stars, other echinoderms and comb jellies. [3] [6] The roughhead grenadier is a slow growing fish.
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). [3] 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 abyssal grenadier's body is ...
Macrouridae is a family of deep sea fish, a diverse and ecologically important group, [2] which are part of the order of cod-like fish, the Gadiformes.The species in the Macrouridae are characterised by their large heads [3] which normally have a single barbel on the chin, [4] projecting snouts, and slender bodies that taper to whip-like tails, without an obvious caudal fin [3] but what there ...
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 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]
