Lanternfish

Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 14; Analspines: 0; Analsoft rays: 13 - 15

High-oceanic species (Ref. 4066). Found between 425-750 m during the day and at 40-500 m at night, with maximum abundance at 75 m (Ref. 4479). Off southern Brazil found between 500-900 m during the day and 25-300 m at night. (Ref. 47377).

High-oceanic species (Ref. 4066). Found between 425-750 m during the day and at 40-500 m at night, with maximum abundance at 75 m (Ref. 4479). Mesopelagic (Ref. 58302). Specimens reach sexual maturity at a length of 5.4 cm. Off southern Brazil found between 500-900 m during the day and 25-300 m at night. (Ref. 47377).

Bolinichthys photothorax

This moderately large species reaches maturity at 50–60 mm and grows to about 73 mm (Hulley, 1981). The Ocean Acre collections contain 15 specimens (20–60 mm) of B. photothorax, which is a tropical-semitropical species found mainly to the south of the study area (Nafpaktitis el al., 1977). The species probably is an expatriate in Bermuda waters, where presumably it does not reproduce. Juveniles were 30–46 mm, subadults 44–57 mm, and the only adult (a male) 60 mm.

Bolinichthys photothorax is a “rare” lanternfish in the study area, being represented by 15 specimens in the collections (Table 23). Five specimens were taken in discrete-depth samples: in winter during daytime a juvenile at 601–650 m, and at night a subadult at 151–200 m; in April at night a juvenile from 151–200 m; in late spring during the day a subadult at 751–800 m; and in late summer at night a juvenile at 151–300 m. In late summer, open Engel trawls caught eight specimens (40–60 mm), six from the upper 200 m at night and two from maximum depths of 750–800 m during daytime. The remaining two individuals were caught in late summer in open IKMT's towed at maximum depths of 550 m at night and 750 m at dawn.

44.7°N to Brazil, with extensions to Argentina

Occasionally found in Canadian Atlantic waters. Found at depths of 425- 750 m during day; at depths of 40- 500 m during night.
