Etymology: Chauliodus: Greek, chaulios, chaulos, chaunos = to be with the mouth opened + Greek, odous = teeth (Ref. 45335). More on author: Bloch, Schneider.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 200 - 4700 m (Ref. 74511), usually 494 - 1000 m (Ref. 28981). Deep-water; 70°N - 56°S, 180°W - 180°E
Warm and temperate parts of all oceans but with several distributional gaps in the southern central Atlantic, northern Indian Ocean, eastern Pacific north of the equator, etc. Also found in the western Mediterranean (Ref. 4759). South China Sea and East China Sea (Ref.74511).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm SL male/unsexed; (Ref. 559)
Inhabits deep oceanic waters to more than 1,000 m depth; may migrate to near-surface waters at night (Ref. 4759). Up to depth of 1800 m (Ref. 47377). Depth range 473-1192 m in the eastern Ionian Sea (Ref. 56504). Meso- and bathypelagic from near the surface to 2800 m (Ref. 58302). Oviparous (Ref. 5951). Feeds on midwater fishes and crustaceans (Ref. 4759); mainly on myctophids (Ref. 5951). Lipid content is 2.4 % in fresh body weight and wax ester is 7.2 % in total lipids (Ref. 9193). Minimum depth from Ref. 58018.
