Macrouridae (Grenadiers or rattails)
Etymology: Coryphaenoides: Greek, koryphaina = dolphin fish + Suffix oides = similar to (Ref. 45335); armatus: From 'cyklos' meaning circle and 'lepis' meaning scale (Ref. 6885).
Environment: milieu / climate zone / depth range / distribution range
Ecología
marino batipelágico; rango de profundidad 282 - 5180 m (Ref. 50610). Deep-water; 65°N - 61°S, 180°W - 180°E (Ref. 1371)
Worldwide: marginal to the Southern Ocean (Ref. 5171).
Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 102 cm TL macho / no sexado; (Ref. 1371)
Espinas dorsales (total): 2; Radios blandos dorsales (total): 123-124; Espinas anales 0; Radios blandos anales: 115. The head is large; the eyes also large. The snout is elongated, somewhat conical; the mouth is small and inferior. The body tapers from behind the first dorsal fin. The light organ extends past midway between the anal origin and the ventral insertion. Color is uniformly brownish, except for the abdomen which is bluish.
A deep-slope upper continental rise species, common in deep waters of most oceans (Ref. 1371). Bathypelagic (Ref. 58426). Feeds on a variety of benthic invertebrates (especially crustaceans and holothuroids) when young, switching to primarily mesopelagic and bathypelagic fish, and sea urchins and cephalopods as adults (Ref. 1371). Sex ratio was 2.6:1 male to female (n = 449) in the Rockall Tough, N.E. Atlantic (Ref. 40742).
