Actinopteri (ray-finned fishes) > Scombriformes
(Mackerels) > Caristiidae
Etymology: Caristius: Name presumably named after Carystus, a demi-god of Greek mythology.. More on author: Borodin.
A further revision of caristiid taxonomy will establish the correct genus for the species (see Britz & Hartel, 2012, Ref. 92346).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 100 - 420 m (Ref. 6643), usually - m (Ref. ). Deep-water; 0°C - ; 76°N - 56°S, 137°W - 31°E
Atlantic Ocean: off Greenland and Lüderitz, Namibia. Also from Falkland Islands (Ref. 47881). Northeast Pacific: British Columbia, Canada. Western Indian Ocean: off Durban, South Africa.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 6643)
soft rays: 18 - 21;
Vertebrae: 35 - 38. This species is distinguished from C. macropus and C. meridionalis. by having fewer and larger teeth (25 or fewer in each jaw and 4-7 in palatine vs. 18 or more and 3-13, respectively) and fewer vertebrae (35-38 vs. 37-41); from C. digitus by the absence of a series of fingerlike papillae inside the opercle (0 or 1 papilla in C. fasciatus), the short conical pharyngeal teeth (vs. elongate pharyngeal teeth), and fewer gill rakers (18-21 vs. 22-26) (Ref. 94277).
Minimum depth reported (Ref. 27121). From catches of mature females and juveniles, spawning apparently occurs on the periphery of subtropical waters (in the Sargasso Sea, in the zone of the Gulf Stream and off the Azores) (Ref. 95096).
