Actinopteri (ray-finned fishes) > Stomiiformes
(Lightfishes and dragonfishes) > Phosichthyidae
Etymology: Vinciguerria: Because of Decio Vinciguerria, Italian ichthyiologist from Genova, 1856-1934 (Ref. 45335). More on authors: Jordan & Williams.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 20 - 5000 m (Ref. 4470), usually - 400 m (Ref. 3988). Deep-water; 0°C - ; 42°N -
Western Central Atlantic: Florida (USA), Cuba and the Antilles, including the Gulf of Mexico and the Caribbean (Ref. 26340). Eastern Atlantic: 42°N to the tropical region. Northwest Atlantic: Canada (Ref. 5951). Indo-Pacific. Southeast Pacific: Chile (Ref. 9068). South China Sea (Ref.74511).
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.4, range 3 - ? cm
Max length : 5.3 cm SL male/unsexed; (Ref. 51999); common length : 3.7 cm TL male/unsexed; (Ref. 56527)
soft rays: 13 - 16. Dorsum dark, flanks silvery; upper pectoral and outer caudal speckled (Ref. 3988). Two suborbital photophores present, anal fin originated beneath the middle or latter half of the dorsal fin (Ref. 37473).
Epi- to abyssopelagic (Ref. 58302) but usually mesopelagic, mainly found at 200-400 m by day and upper 100 m by night (Ref. 4778). Both juveniles and adults exhibit diel vertical migration (Ref. 4778). Feeds mainly on copepods, feeding intensively in the afternoon to early evening (Ref. 4778). Adult photophore complement attained at about 18-20 mm SL (Ref. 4778).
